Thermo-hygrometer for compressed air measurement

Thermometer, hygrometer is designed for measurement and datalogging of temperature, relative humidity for compressed air up to 25 bars with 1m cable into the internal non-volatile memory.

Free PC program enables to transfer recorded data to the computer for evaluation. LCD backlight.

Data logger is connected to the PC through USB cable only for data trasfer from the memory. During connection with the PC no measurement and record is enabled.

Simultaneous reading of temperature and relative humidity, dew point temperature reading selectable, external temperature-humidity probe with 1meter cable. Cable lengths 2 and 4 meters available optionally. Probe diameter is 18mm, length 135mm.
