SL54USB - USB Temperature And Relative Humidity Data Logger

The SL54USB and SL54USB-A record temperature and relative humidity. The USB data loggers plug directly into the USB port of the computer for configuration. They are then removed from the USB slot and placed where monitoring is required. When the monitoring is complete, the data logger is placed back in the USB slot for data retrieval. They have the ability to record up to 8,000 data points and have a measuring temperature range of -10°C to +85°C and 0 to 95%RH.

Both the SL54USB and the SL54USB-A have a temperature accuracy of ±0.5°C. The SL54USB has an  relative humidity accuracy of ±5%RH and the SL54USB-A has an improved relative humidity accuracy of ±2%RH and is supplied with a UKAS 17025 traceable calibration certificate.

Both SL54USB data loggers are fully compatible with our user friendly software - TempIT. TempIT-LITE is free of charge and allows the logger to be set up and the data read and displayed in graphical format. Graphs can be stored, printed or retrieved at a later time. TempIT-LITE can be up-graded to TempIT-PRO which provides various additional features such as data table view, export data to spreadsheet, email graphs, F0 and A0 calculations, and automated mean kinetic temperature (MKT) calculations etc.

The SL54USB will also calculate dew point and absolute humidity.
