The SL54M is a low 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 SL54M can operate in a temperature range of -10°C to +50°C and up to 100%RH. The SL54M-A is identical to the SL54M but with an improved relative humidity accuracy of ±2% and is supplied with a UKAS 17025 traceable calibration certificate. 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 SL54M and SL54M-A also calculate dew point and absolute humidity.
The USB Interface lead and software are not included with this temperature data logger but you can find details of these below.
