LOW COST temperature data logger that measures from -40°C to +85°C with an accuracy of ±1.0°C. Starter kits are available with either two or five data loggers, the USB Interface and the TempIT-PRO software.

The SL51T is a self contained, multiple use, temperature data logger with the ability to record up to 2,000 temperatures over the temperature range of -40°C to +85°C with an accuracy of ±1.0°C. The SL51T-A is supplied with a calibration certificate and is available from the drop down menu shown just below the price. If you require a better level of accuracy, the SL52T is available with ±0.5°C accuracy.

Being only 17mm in diameter and 6mm thick, the SL51T is incredibly small, about the same size as a watch battery, which enables it to be inserted into small items and packages. The memory can hold up to 2,000 readings and can be cleared at the start of each data logging session, allowing the data logger to be reused over and over.

The SL50-INTERFACE-USB interface lead is required to connect to the USB port of the computer and is compatible with the user friendly, and FREE OF CHARGE, TempIT-Lite operating software. This enables the logger to be set up and the readings downloaded from the data logger and displayed in a graphical format. Data can also be saved 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, graph annotations, and automated MKT, F0, A0 and PU calculations.

SL51T Starter Kits Are AvailableStarter kits with either two or five SL51T temperature 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.
