Thermohygrometer Testo 635-1
Thermohygrometer Testo 635-1. A device for measuring air humidity, equilibrium material moisture and pressure dew current in compressed air systems. The device display can display data from three humidity or temperature probes. Measurement data can be transferred to the Testo printer via an infrared port. It is also possible to print data, for example, once per minute during cyclic printing. The device instantly displays the difference in dew point between the air temperature and the wall surface when analyzing the humidity of walls and ceilings. Precision probes down to -60 °C are used to measure pressure dew point in compressed air systems. The humidity sensor developed by Testo is recognized worldwide and has outstanding characteristics in terms of accuracy, long-term stability, temperature resistance and robustness. Features: included in the State Register of Measuring Instruments of the Russian Federation FSIS "ARSHIN"; measurement of humidity, equilibrium moisture content of the material, pressure dew point; cyclic data printing on a testo printer, for example, once a minute; calculation of dew point temperature and temperature difference.
