Monicon IR80CO2 Gas DetectorThe Monicon IR80 CO2 gas detector offers immediate, reliable warnings to dangerous concentrations of carbon dioxide.

Using an NDIR (non dispersive infra red) gas sensor, the IR80 is designed to present the convenience of operating as a stand alone instrument or in conjunction with a controller, dependant on the application. Typical applications of the IR80 include breweries, food processing, mushroom farming and laboratories.

Simple, Computer-assisted Operation Housed in an attractive, compact enclosure the IR80 CO2 detector can be configured and calibrated by just one person. The simple button operation of the IR080 allows it to be fully user programmable whilst the on-board computer assists the calibration - meaning there’s no need for physical adjustment during the calibration procedure.

User Customisation for Alarm SettingsThe gas concentration is indicated on a rugged 8-character alphanumeric display which also indicates instrument status

Project Driven, Bespoke Solutions Using our expert engineering knowledge, the a1-cbiss project team produce the design, specify equipment and integrate the system before it’s delivered to site by our service and maintenance team
