The temperature of food has a critical influence on product quality and consumer health. In order to ensure food safety and prevent the proliferation of germs, it is necessary to monitor food temperatures. During transport, upon receipt and throughout storage, make sure that cooling compliance is uninterrupted by using both infrared and core temperature measuring technology. The testo 104-IR infrared and penetration thermometer helps you do this. This instrument offers:
- Fast scanning of the goods delivered using infrared measuring technology
- Immediate inspection of critical values via fold-out penetration probe
- Fast and easy display of the measuring range via 2-point laser
- Durability and a waterproof housing
- HACCP-compliant measurement
