Fridge and freezer monitoring

This digital thermometer places a waterproof external sensor inside the fridge or freezer while the magnetised main unit stays on the outside. It records maximum and minimum temperatures over a 24 hour or full period history. The backlight stays on for 10 seconds for dark areas. It runs on 2 AAA batteries and includes a low battery indicator.

Replaces basic analogue dials

Upgrade from a simple dial thermometer when you need programmable high and low temperature alarms with a mute option and LED alerts. The jump is worth it if you want Celsius and Fahrenheit switching, max and min memory, and a sensor cable that reaches the centre of the compartment for accurate readings. The unit has been sold since 2016 for home, restaurant and RV use.

Check sensor placement and environment

Verify you can route the sensor cable to the centre of the fridge or freezer without pinching it against the door seal. Confirm the application is fresh water only if used for aquariums or reptile habitats. Ensure the main unit remains dry because it is not waterproof. The magnet requires a ferrous exterior surface for mounting.

Questions about this item

Where do I place the external sensor and the magnetised main unit in a fridge or freezer?

Put the waterproof sensor in the centre of the compartment, not on the door or against food, and attach the main unit to the outside with its magnet.

How do I install the batteries and what step do people miss?

Insert two AAA batteries, then remember to switch the power on and select Celsius or Fahrenheit before setting any alarms.

What ongoing maintenance will this thermometer need?

Replace the two AAA batteries when the low-battery indicator appears; the waterproof sensor handles condensation and spills without extra care.
