Product Details & Documents

Use the humidity/temperature probes (with an appropriate measuring instrument) for the reliable measurement of relative humidity and temperature. Humidity sensor is durable and traceable to international humidity standards, such as ILAC, PTB and NIST. Thus, even after years of use you can still count on measurement results that are reliable and correct.
