The SL54TH is our lowest cost temperature and relative humidity data logger. It is self contained and self powered with the ability to record up to 8,000 data points. The SL54TH can operate in a temperature range of -20°C to +85°C and up to 100%RH with an accuray of ±0.5°C and ±5% relative humidity. The SL54TH-A has an improved relative humidity accuracy of ±2% and an imporvoed temperature accuracy of ±0.1°C. The SL54TH-A is supplied with a UKAS traceable calibration certificate.

They are very small (about the same size as a watch battery) which enables them to be inserted into small items and packages.



The SL50R Button Reader™ interfaces to the USB port of a PC and is totally compatible with the user friendly, TempIT-LITE operating software which enables the logger to be set up and the data read and displayed in graphical format. Data can be stored and retrieved at a later time. The software can be up-graded to TempIT-PRO which provides various additional features such as data table view, export data to spreadsheet, email graphs and automated MKT Calculations etc. The TempIT software also automatically calculates dew point from the measured temperature and relative humidity readings.
The SL54TH and SL54TH-A also calculate dew point and absolute humidity.

SL54TH Starter Kits Are AvailableStarter kits with either two or five SL54TH or SL54TH-A temperature and relative humidity data loggers, the USB interface lead and a single computer licence of the TempIT-PRO software are available from the drop-down menu shown just below the price above.
