testo 635-1, humidity/temperature measuring device, incl. calibration protocol and batteries. The measuring device for measuring humidity, material equilibrium moisture and for measuring the pressure dew point in compressed air systems. Wireless, i.e. with measurement data transmission by radio, up to 3 temperature or humidity sensors can be displayed. The measurement data can be transferred to the Testo log printer via infrared. With cyclical printing, the measurement data can be output once a minute, for example.For analysing the humidity on ceilings and walls, the testo 635 directly displays the dew point difference between the room air and the wall surface.Pressure dew points down to -60°C tpd are available for analysing the pressure dew point in compressed air systems. The humidity sensor developed by Testo itself is proven worldwide and offers outstanding properties in terms of precision, long-term stability, temperature resistance and robustness. • Connection of 3 wireless sensors• Measurement of air humidity, material equilibrium humidity and pressure dew point in compressed air systems• Display of dew point distance, minimum, maximum and average values• Cyclical printout of measured values, e.g. once per minute Technical data: Measuring device:Storage temperature: -30 … +70 °COperating temperature: -20 … +50 °CHousing material: ABS/TPE/metalDimensions: 220 x 74 x 46 mmBattery life: 200 hBattery type: alkaline-manganese, AA type Capacitive humidity sensor:Measuring range: 0 … +100 %RHResolution: 0.1 %RH NTC:Measuring range: -40 … +150 °CAccuracy: ±0.2 °C (-25 … +74.9 °C)±0.4 °C (-40 … -25.1 °C)±0.4 °C (+75 … +99.9 °C)±0.5% v.
