<a href="https://unitestcalibration.com/service/temperature-sensor-and-humidity-sensor-singapore/">Sensors that measure humidity</a> must be calibrated regularly to keep working within specifications. Calibration of humidity sensors is usually done using an instrument called a humidity chamber.

Unitest Calibration’s lab uses a temperature and humidity chamber as a controlled environment and a set of temperature and humidity probes with displays as a reference. By comparison, all calibrations are performed relative to ITS-90 (International Temperature Scale 1990).</p>
