Wireless Fridge Thermometer FM25 Digitron Details:

The FM25 is different from many other traditional fridge thermometers with its wireless technology, which allows temperature monitoring of food without the need to open the refrigerator door.

Temperatures from the RF sensors which are placed inside your refrigerator or freezer are sent wirelessly and displayed on the base station.

The base station can be attached to the cabinet magnetically or positioned upright using the retractable stand. The display refreshes every 8 minutes.

The FM25's alarms, both audible and visual, activate if the temperature deviates from the pre-set maximum and minimum thresholds for more than 15 minutes this feature prevents false alarms during restocking, ensuring you're alerted only to significant temperature fluctuations that could compromise product integrity.

FM25 Wireless Thermometer Key Features:

- Remote sensors wirelessly transmit data to the base station.
- Dual-channel display for simultaneous monitoring.
- The temperature can be displayed in either Celsius or Fahrenheit
- With an accuracy within +/- 1°C
- Multiple mounting options for the base: magnetic, wall-mounted, or freestanding.
- Remote sensors come with spring-loaded clips for secure placement inside the fridge/freezer or optional suction cups.
- Audible and visual alarms with a 15-minute delay to avoid unnecessary alerts.
- Operates on a license-free frequency.
- Includes a low battery indicator for maintenance convenience.
