Humidity Data Loggers

Signatrol provide a range of temperature and relative humidity data loggers. From the miniature SL54TH right through to our SpYdaq wireless monitoring solution.

All of these data loggers all have internal temperature and relative humidity sensors. The SL7000 data loggers also have the ability to add external temperature and relative humidity sensors allowing two locations to monitored at the same time.

The SL54TH, SL54TH-A, SL54USB and SL54USB-A also calculate dew point and absolute humidity.

The SL54TH-A and SL54USB-A are supplied with UKAS 17025 traceable calibration certificates. The SL54M includes a rubberised holder with mounting eye and strong magnet to hold the data logger in place.
