Stationary Measurement Solution for Air Conditioning and Process The Testo humidity sensor The Testo humidity sensor has been in use for over 15 years, and has been continually improved - from the very beginning, the focus was on the two accuracy parameters measurement uncertainty and long-term stability. Owing to the design of the humidity sensor and the high degree of stability in Testo production and calibration, it is possible to guarantee a measurement uncertainty of 2 %RH, optionally also 1 %RH. In addition to this, the humidity sensor also has a high level of longterm stability. Thi
