The SL54TH is our lowest cost temperature and relative humidity data logger. It is a 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. They are very small (about the same size as a watch battery) which enables them to be inserted into small items and packages. The SL54TH-A is identical to the SL54TH but with an improved relative humidity accuracy of ±2%.

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.
