Description
4G KP GSM Temperature, Humidity & Power Status Monitor, supplied with a 20 metre Probe, communicates with up to 10 x key-holders by SMS & Telephone. Easy to program using SMS or APP.

- Humidity: 0 - 99 RH% (accuracy 3%).
- Power Failure: Low & High Voltage Options (ideal for power failure, or solar panel monitors).

The system can be programmed to contact the key-holders if the pre-selected High or Low Temperature has been reached.
Humidity:
The system can be programmed to contact the key-holders if the pre-selected High or Low Humidity has been reached.
Power:
The system can be programmed to contact key-holders if the pre-selected High or Low voltage has been reached, this allows it to be used as a standard mains power failure alert, or a monitor for applications such as Solar Panels (monitoring the batteries).

The system can be programmed to automatically send a status report every day, or pre-selected duration (between 1 to 998 hours).
