Temperature probes connect to a rechargeable radio logger and send measurements through a compatible master. Cold-chain teams compare three cargo zones, examine the history and organise checks on changed conditions.
Separate temperature records help cold-chain staff examine conditions across the zones inside a cargo chamber. Envotech's RadioSecure WTS, the wireless temperature sensor unit, connects to as many as three wired probes. Each probe represents its own zone, bringing local readings into the compatible master and hosted monitoring workflow.
The WTS logs temperatures at a 30-second interval and relays the record through a proprietary local radio connection. A RadioSecure master receives the values for onward reporting in the connected system. A rechargeable battery operates the temperature unit, and an external 12 V DC supply is also supported. The unit can be permanently installed in the chamber or mounted using a magnetic fixing, with probe cables reaching the selected measurement locations.
Staff examine the separate zone readings and their history to identify a temperature change that warrants a cargo or refrigeration check. The application presents records in charts and tables, retaining the measurements available through the installed master. Technical support covers hardware and software integration for the selected arrangement. The physical probe positions define which parts of the load the records represent, and the operating team uses those records when choosing the required handling response.

One WTS connects to three wired temperature probes, providing readings for three selected zones.
It uses a rechargeable battery and supports an external 12 V DC supply. Permanent and magnetic mounting arrangements are available.
The WTS relays readings by local radio to a compatible RadioSecure master, which supplies the connected system reporting path.
It logs temperature at a 30-second interval before relaying the record through its local radio connection.
