SL50 Series Magic Button miniature loggers are fully sealed, stainless steel units with the ability to record up to 8,000 data points and operate in a temperature range of -40°C to +125°C, depending upon the model chosen. The devices are very small (about the same size as a watch battery) which enables them to be inserted into small items and packages.

Each device has a unique registration number laser engraved on both the internal chip. Water tight enclosures are available that allow the logger to be used in hostile environments. An optional battery powered printer allows the data to be printed directly from the logger.

A USB interface reader allows the device to be connected to a PC for the data to be downloaded to be further analysed using TempIT-Lite software downloadable from this site.
