Product Highlights

TRH320: USB temperature and relative humidity sensor.

Part of the TRH series of measuring instruments, the TRH320 is specifically designed for environmental temperature and humidity acquisition. With its factory calibrated, linearized and temperature compensated digital sensor chip, it is field interchangeable. Thanks to its precision electronics, extremely small variations in temperature and humidity can be acquired using a standard USB port. The compact probe eases integration, even in space-constrained locations, and the built-in particle filter provides protection against dust, soot and other contaminants.
