The Thermapen Professional thermometer measures temperatures over the range of -49.9 to 299.9 °C using a stainless steel probe. Readings can be taken in Celcius or Fahrenheit. It is accurate, quick to take a reading (3 seconds) and easy to use. The casing, which has a Biomaster additive to cut down on bacterial growth, can be washed and a rubber seal minimises the chance of dust, water or food getting into the thermometer.
The thermometer requires one AAA battery and has light and motion sensors to adapt to conditions and conserve battery life.
