The SL55T-A is a self contained single channel, button data logger with the ability to record up to 8,000 temperature points over the range +15°C to +140°C. The SL55T-A functions the same as the SL55T but with an increased accuracy over the range +80°C to +140°C. 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 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, F0, A0 and PU calculations etc.

 Please note: If ordering online, there will be a slight delay in despatching the items due to the additional calibration procedure required to convert the 'standard' SL55T to the SL55T-A 

Each model has specific advantages: SL51T - Lowest cost, -40°C to +85°C measuring with ±1.0°C Accuracy SL52T - Larger memory and faster sample rates. ±0.5°C Accuracy SL53T - High temperature 0°C to +125°C SL55T - Highest temperature +15°C to +140°C SL55T-A - Improved accuracy of ±0.5°C from +80°C to +140°C The SL52T, SL53T, SL55T and SL55T-A also have a 'start when alarm' function which inhibits data logging until the data logger has been in an alarm condition. Ideal for temperature related fault finding. Starter kits are available for all models. The Starter kits contain up to five data logging buttons, the communication interface, a single plastic holder and a copy of the TempIT-Pro software - offering good savings if all items were purchased separately. All SL50 series data loggers and starter kits are available to purchase online by clicking on the relevant 'cart' button to the right.
