The USB-TRH300 is specifically designed for environmental
temperature and humidity acquisition. The digital sensor chip
used in the USB-TRH300 probe is fully calibrated, linearized
and temperature compensated at the factory making this
sensor field interchangeable. Thanks to its precision elec-
tronics, extremely small variations in temperature and humid-
ity can be detected. This makes the USB-TRH300 suitable
for a wide range of applications. This unit is designed using a
compact probe form factor for easy integration even in space
-constrained locations.
