The PT1000 GSM ProTherm system is a GSM wireless controller device for monitoring and logging system temperatures. The unit continuously monitors the two input temperature channels and if the temperatures exceed a preset level, an SMS alert is sent to the desired mobile(s). The unit also alerts the user of power failures. It takes two PT1000 sensors and accurately measures temperature to 0.1°C. It is simple to install requiring only a single connection to the supply.

The PT1000 controller is simple and quick to use. It can be programmed from a mobile phone anywhere in the world. The controller command set is in plain English making it easy to remember the commands. Once the unit has been set up, no further adjustment is necessary. In the event of a supply failure, the PT1000 has integral battery back-up which can keep the system operating for up to 24 hours.

An optional feature is temperature logging, where the temperature can be logged to a server via GPRS and displayed graphically via the web on-demand. The system can log more than 30 days on-board without GPRS access to the internet.
