TESTO has released the Hygrotest 650 temperature humidity sensor. It guarantees long-term measuring stability under extreme conditions and remains precise at relative humidities of over 90%. This has made operating temperatures up to 1800ºC possible.
The transmitter has a precision of ±1% relative humidity. It has an easily cleaned metal housing. The length of the cables and probes may be adapted to suit requirements. Various humidity variables such as dew point, absolute humidity, relative humidity or psychrometer humidity may be calculated.
The instrument is suitable for use in cleanrooms, semiconductor production, the automotive industry, engine test beds, painting plants, drying systems and for the production of fuel cells.
