The ThermaData Studio software is supplied as a FREE download. Please note: when initially ordering non WiFi loggers, it is necessary to order at least one suitable communications cable.

ThermaData WiFi loggers Use the unique ID of each logger to create a secure connection between the logger and ThermaData Studio software, that can be accessed and viewed anytime and anywhere with an internet connection. Each logger communicates directly to the WiFi router at set intervals to push data through the internet into ThermaData Studio. The information is available to be analysed and exported into a report format.
