With this digital thermometer you can measure the temperature inside a fridge or alternatively measure room temperature.

The 810-225 thermometer is designed to be placed outside a fridge where the internal sensor will calculate room temperature. A flexible remote probe with 1m cable is included plus suction pads and a mounting bracket for placing inside the fridge. You can decide which measurement is displayed on the thermometer by pressing the ‘Probe’ button on the front.

This digital thermometer can measure temperature from -49.9 to 69.9°C with resolution of 0.1°C and accuracy of ±1°C. A built-in MAX/MIN function is included, allowing the user to calculate maximum and minimum temperatures taken over a period of time.

Want to be alerted when temperature is outside the norm? Use the 810-225’s built-in adjustable high/low alarm function to do this.
