  • 2 in 1 integrated probe and infrared laser 
  • Waterproof housing (IP65) 
  • HACCP Certified 
  • For carrying out surface and core temperature measurements 
  • The Testo 104-IR food safety thermometer is ideal for carrying out temperature and food safety checks. And because it fits snugly in any pocket, it’s always there when you need it to carry out checks on incoming goods, spot checks during transport or food inspections in the retail industry. 
    • A measuring instrument for determining surface and core temperature with intuitive operation.

    Food thermometer and infrared thermometer rolled into one

    The Testo 104-IR is equipped with a high-precision 2-point laser and 10:1 optics which show the exact measurement range and allow you to carry out quick and accurate non-contact surface temperature measurements. The 2-in-1 thermometer is especially useful for checking incoming goods and for scanning the surface temperature of individual food products as well as whole pallets.

    The folding probe thermometer is used to measure the core temperature of food products like meat and sausage meat for example. It generally comes into play when the infrared surface measurements are not within the prescribed thresholds. The probe can be folded away when not in use to protect against breakage.

    Quick and easy to use. Tried and tested in the field

    The food thermometer is immediately activated when the probe sensor is folded down. Simply press a key to start the infrared measurement. The results are presented on a large, easy-to-read display. Because the keys themselves are easy to understand, there is no need to instruct individuals on how to use the thermometer. Last but by no means least, the food safety infrared thermometer is waterproof and IP65 rated.

    Temperature checking for incoming goods and during transport and storage

    The temperature of foods has a crucial influence on the formation and proliferation of germs and therefore on product quality and consumer health. In order to ensure food safety, there is therefore an obligation to monitor the temperatures of foods and to check that cooling chain compliance is uninterrupted. Among the measures used to achieve this is checking temperature on receipt and during transport and storage of the goods. The testo 104-IR infrared and penetration thermometer helps you to do this. It offers:

    • Fast scanning of the goods delivered using infrared measuring technology
    • Immediate checking where values are critical via fold-out penetration probe
    • Simple display of the measuring range via 2-point laser
    • Robustness thanks to a waterproof housing
    • HACCP-compliant measurement
