General Information

2.3 General Product Overview

DANGERThe 8362 sc High Purity Water pH or ORP sensor is not approved for hazardous locations.

The 8362 sc High Purity Water pH/ORP panel is preplumbed and includes the 8362 sc High Purity Water Sensor (Figure 1), digital electronics junction box, flow meter, and mounting assembly. The 8362 sc High Purity Water pH/ORP Sensor contains two electrodes; one for pH or ORP and the other for temperature.

The water runs through the 8362 sc High Purity Water Sensor then through a flow meter, finally exiting the panel. The flow meter adjusts the sample stream from 0–300 mL/min (0–300 cc/min.). The sensor then sends a mV signal and a temperature signal through separate cords to a junction box which translates the analog pH/ORP and temperature signal from the sensor into a digital signal to be read by the digital controller. Refer to Specifications on page 5.

The 8362 sc High Purity Water panel is a manufactured panel to simplify and enhance the connection between sensor and controller. It uses a self-pressurizing reference electrode that introduces a constant flow of electrolyte into the sample stream. This constant flow of electrolyte reduces the effects of electrolyte oscillations that cause reference junction potential phase shifts that are found in other measuring systems. In addition, the electrodes are housed in a special stainless steel housing and unique conductive flow chamber to greatly reduce the effects of streaming currents that cause pH or ORP measurements in high purity water to drift.

2.3.1 Measurement Principle

This 8362 sc High Purity Water pH/ORP system is specially designed for continuous measurement of pure and ultra-pure water. It uses a reference electrode similar to the measuring electrode to minimize the impedance of the measurement. The body is made of 316 L stainless steel, which protects the measurements from electrostatic and magnetic disturbances. The circulation chamber was designed without a retention zone to avoid interference from CO2 dissolution, air bubble accumulation, or insoluble deposits accumulation (iron oxide, residues salted out by resins, etc.).

Installation

3.3 Sample Connections

1. Connect the sample stream flow to the sample-in port.

2. Connect a drain tube to the sample-out port.

Note: It is not recommended to run the sample stream back into the main flow stream.

3. Introduce the sample and visually check the measurement chamber for bubbles that could disturb the measurement.

4. Adjust the flow to between 100–300 mL/min (100–300 cc/min) for best results.

3.4 Flow Rate and Pressure

Observe the following for optimum operation:

• Keep the flow constant at a rate between 100–300 mL/min (100–300 cc/min) at a maximum pressure of 4 bar (58 psi) for best operation.

• Keep the drain line as short as possible to avoid back-pressure.

• Earth ground the flow chamber to protect it from external electrical noise (Figure 3).

• Do not allow the flow chamber to become empty. Keep the glass electrode bulb in water to avoid electrode damage.

• Use the protective cap filled with KCl (3 M) on the pH or ORP electrode for storage of up to one year. Never store your electrode in air even if it is in the flow chamber.

3.5 Connecting to the Controller

Connect the extension cable from the controller to the panel with the quick-connection fitting on the side of the junction box (Figure 3). See the controller user manual for detailed information on configuring and using the controller.

4.7 pH Calibration

DANGERHandling chemical samples, standards, and reagents can be dangerous. Review the necessary Material Safety Data Sheets and become familiar with all safety procedures before handling any chemicals.

The manufacturer offers one and two point automatic and manual calibrations for pH. An automatic calibration identifies the buffer table corresponding to the chosen buffer and automatically calibrates the probe after it stabilizes. A manual calibration is performed by placing the pH sensor in any buffer or sample with a known value and then entering that known value into the controller.

The value of the sample used in the manual calibration may be determined by laboratory analysis or comparison reading.

4.7.1 pH Calibration Procedure

For best results with a new sensor, allow sample to flow through the measurement chamber at least 10 hours before calibrating. For precise calibration of the pH electrode, the two point calibration method is required. The manufacturer recommends using a pH 4 and pH 7 buffer. The pH 7 buffer is required for a first standardization and pH 4 (or pH 10) buffer solution is required to calibrate the electrode slope. See section 4.7.2 for additional buffer information. Use the buffers as follows:

1. Holding the flow chamber nut in position, unscrew the flow chamber. See Figure 7.

2. Empty the water from the flow chamber and rinse with demineralized water.

3. Rinse the electrodes with demineralized water.

4. Fill the flow chamber with the pH 7 buffer and reinstall. Always use fresh buffers.

5. Calibrate the first point following the Two Point Automatic Calibration Method on page 25.

6. Remove the flow chamber, empty the first buffer and rinse the flow chamber and electrodes with demineralized water.

7. Fill the flow chamber with the pH 4 (or pH 10) buffer and reinstall.

8. Calibrate the second point following the Two Point Automatic Calibration Method on page 25.

9. Remove the flow chamber, empty the second buffer and rinse the flow chamber and electrodes with demineralized water. Reinstall the flow chamber.

10. Turn on the sample stream to the flow of 100–300 mL/min (100–300 cc/min). Allow the sample to flow through the assembly for a minimum of one hour.

11. Using a qualified standard meter do an overflow method sample measurement, see Figure 8 on page 31.

12. Compare this reading with the reading on the controller. If the reading is different, do a single point sample calibration on the controller so that it reads the same as the standard meter.

Figure 7 Measurement System—Removing the Flow Chamber

4.7.2 Buffer Solutions (pH)

The pH of buffer solutions are dependent on temperature. The nominal pH values are referenced to a temperature of 25 °C (77 °F). Refer to Table 3 for NIST standard buffer solutions and DIN buffer values for a variety of temperatures. Always check the buffer table for the value of the buffer in use at the operating temperature.

4.8 ORP Calibration

The manufacturer offers a one point manual calibration for ORP. The value of the sample used in the manual calibration may be determined by laboratory analysis or comparison reading.

4.8.1 ORP Calibration Procedure

For a precise calibration of the ORP electrode, a standard solution is required. The manufacturer recommends using a one point standard solution calibration. Use the solution as follows:

1. Holding the flow chamber nut in position, unscrew the flow chamber (Figure 7 on page 24).



4. Fill flow chamber with the standard solution and reinstall.

5. Calibrate following the one-point calibration method (section 4.8.2).

6. Remove the flow chamber, empty the solution and rinse the flow chamber and electrodes with demineralized water.

7. Reinstall the flow chamber.

8. Turn on the sample stream to the flow of 100–300 mL/min (100–300 cc/min).

9. Allow the sample to flow through the assembly for a minimum of one hour.

10. Using a qualified standard meter do an overflow method sample measurement, (Figure 8 on page 31).

4.9 Overflow Sample Method (ASTM Method) Procedure

1. Take a side-stream sample from a tap as close to the 8362 sc High Purity Sensor as possible.

2. Introduce the sample to the bottom of a large (500 mL) beaker through a clean tube extending to the bottom of the beaker. (Make the tube as short as possible between the beaker and the sample tap.)

3. Place the electrode from the standard meter into the beaker (Figure 8). Allow the beaker to overflow to eliminate the possibility of CO2 contamination.

4. Overflow for at least fifteen minutes to allow the standard meter electrode to become clean and the temperature to equilibrate before accepting the reading.

5.7 pH Calibration

DANGERHandling chemical samples, standards, and reagents can be dangerous. Review the necessary Material Safety Data Sheets and become familiar with all safety procedures before handling any chemicals.

The manufacturer offers one and two point automatic and manual calibrations for pH. An automatic calibration identifies the buffer table corresponding to the chosen buffer and automatically calibrates the probe after it stabilizes. A manual calibration is performed by placing the pH sensor in any buffer or sample with a known value and then entering that known value into the controller.

The value of the sample used in the manual calibration may be determined by laboratory analysis or comparison reading.

5.7.1 pH Calibration Procedure

Note: For best results with a new sensor, allow sample to flow through the measurement chamber at least 10 hours before calibrating.

For precise calibration of the pH electrode, the two point calibration method is required. The manufacturer recommends using pH 4 and pH 7 buffer. The pH 7 buffer is required for a first standardization and pH 4 (or pH 10) buffer solution is required to calibrate the electrode slope. See section 5.7.1.1 for additional buffer information. Use the buffers as follows:

1. Holding the flow chamber nut in position, unscrew the flow chamber. See Figure 15.



4. Fill the flow chamber with the pH 7 buffer and reinstall. Always use fresh buffers.

5. Calibrate the first point using the Two Point Automatic Calibration Method on page 43.

6. Remove the flow chamber, empty the first buffer and rinse the flow chamber and electrodes with demineralized water.

7. Fill the flow chamber with the pH 4 (or pH 10) buffer and reinstall.

8. Calibrate the second point using the Two Point Automatic Calibration Method on page 43.

9. Remove the flow chamber, empty the second buffer and rinse the flow chamber and electrodes with demineralized water. Reinstall the flow chamber.

Figure 15 Measurement System—Removing the Flow Chamber

5.7.1.1 Buffer Solutions (pH)

The pH of buffer solutions are dependent on temperature. The nominal pH values are referenced to a temperature of 25 °C (77 °F). Refer to Table 4 for NIST standard buffer solutions and DIN buffer values for a variety of temperatures. Always check the buffer table for the value of the buffer in use at the operating temperature.

Section 7 Troubleshooting

Table 5 General Troubleshooting

Symptom Probable Cause Corrective Action

The electrode does not calibrate.

Bad measuring or reference electrode. Replace defective electrode.

The wiring to the controller is incorrect.Check the electrode cable to controller wiring. Make sure the wire connectors are contacting the metal wires and not the wire insulation.

The controller is defective. Replace the controller.

The readings are erratic.

Air in the sample line.

If a pocket of air passes over or gets trapped at the end of the electrode, the reading becomes momentarily erratic. This usually is remedied by reorienting the electrode so that air bubbles do not block the sensor.

Electrode grounded improperly.Refer to the sensor user manual for proper grounding.

The glass bulb is defective. Replace the electrode.

Streaming potentialGround the solution near the electrode (especially in high purity water).

The response is slow. The sample is cold and/or of low ionic strength.

Raise the temperature of the sample.

Short term drift in the pH reading.

The electrode has insufficient conditioning.

Condition a new or dry electrode for at least 10 hours in the process sample. Perform a calibration after conditioning.
