PRECISION USB TEMPERATURE AND HUMIDITY SENSOR The TRH420 is specifically designed for environmental ◌ OEM ◌ Greenhouse ◌ Server rooms ◌ Manufacturing ◌ Pre-certification ◌ LIMS integration ◌ Humidity control ◌ Scientific research ◌ Building automation ◌ Engineering and R&D ◌ Environmental chamber 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 detected 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.

Each sensor is individually conditioned by the manufacturer of the semi-conductor sensor chips, in the best stable condition and their correction coefficients are recorded in each of them. [3] If water condensation or splashing is possible, it is recommended to install the probe pointing down to reduce the risk of water build-up in the sensor. If water splashing is possible, protect the sensor and cable converter using extra precautions. Extra housing may be required depending on the application. [2]
