COMET C3633 – Thermo-hygrometer with integrated magnetic temperature probe -10 to +60 °C

COMET C3633 – Digital thermo-hygrometer with integrated magnetic surface temperature probe – surface measurement −10 to +60 °C (±0.4 °C), humidity 5–95 %RH (±2.5 %), dew point 

The COMET C3633 is a professional digital thermo-hygrometer with an integrated magnetic surface temperature probe – the ideal solution for precise measurement of surface temperature and ambient climate (temperature, relative humidity, dew point) in mechanical engineering, engine monitoring, pipelines, radiators, heat exchangers, bearings, climate chambers, or anywhere temperature needs to be measured quickly and securely on metallic surfaces without handheld pressure. The strong magnetic probe adheres firmly to iron and steel surfaces without adhesive tape or screws – perfect for rapid checks and continuous measurements.

The internal humidity sensor measures 5 to 95 %RH (±2.5 %RH at 23 °C) and automatically calculates dew point (−40 to +60 °C, ±1.5 °C at T<25 °C and RH>30 %). The integrated magnetic temperature probe measures surface temperature from −10 to +60 °C (±0.4 °C). The acoustic and optical alarm warns immediately when freely adjustable limits are exceeded. The Min/Max memory shows the extreme values since the last reset. The backlit LCD display ensures clear visibility; measuring rate (0.7 to 5 s) and display refresh rate are adjustable. The robust housing (IP20) and battery operation (9 V block or 12 V power adapter with NiMH 9 V battery) make it mobile and independent – battery life approx. 4–6 months.

The thermo-hygrometer is maintenance-free, long-term stable, and comes with a 3-year warranty. The included traceable calibration certificate guarantees maximum measurement accuracy from the factory. Simple operation using keys and a clear menu. Whether used as a mobile test device for service, a stationary monitor on machines, or as a reference instrument in the laboratory – the C3633 stands out for its precision, ease of use, and practical magnetic fixation for fast surface temperature measurement.
