SL50 Miniature RH & Temperature Data Logger

Brand: Signatrol Ltd.

The SL50 series of miniature data loggers comprises of four data loggers: 

The SL51T measures temperature from -40° to 85° C with an accuracy of ±1° C. 

The SL52T operates over the same temperature range of the SL51T, -40° to 85° C but has an improved accuracy of ±0.5° C. The SL53T operates over the range 0° to 125° C with an accuracy of ±0.5° C. 

The SL54TH measures temperature over the range -40° to 85° C and also measures relative humidity from 0 to 100%. 

SL55T-A measures from 15° to 140° C with an accuracy of ±0.5° C from 80° to 140° C. 

All models are available supplied complete with UKAS traceable calibration certificates. 

These models are identified with the -A suffix and in the case of the SL53T-A and the SL54TH-A, are calibrated to give an improved accuracy over the “standard” version. 

All members of the SL50 series are fully compatible with our TempIT software which is available as a free download from the Signatrol website. 

The SL50 series data loggers connect to the computer using the USB interface (sold separately).

There are also a range of accessories available to assist with mounting or protection.
