Temperature data logger that measures from +15°C to +140°C with an accuracy of ±0.5°C. Starter kits are available with either two or five data loggers, the USB Interface and the TempIT-PRO software.

The SL55T-A is a self contained, temperature data logger with the ability to record up to 8,000 temperature points over the range +15°C to +140°C with an accuracy of ±0.2°C from +80°C to +140°C ideal for autoclave verification. The button data loggers themselves are very small (about the same size as a watch battery) which enables them to be inserted into small items and packages.

The SL50-INTERFACE-USB cable interfaces to the USB port of a PC and is totally compatible with the user friendly, FREE OF CHARGE, 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, F0, A0 and PU calculations etc.
