The Infrared Thermometer for the Food Industry – HI99551 is a durable meter that can be used throughout the food industry. The HI99551 offers features such as a quick, one-second response time, HOLD function, and Hanna’s Battery Error Prevention System (BEPS) that will shut the meter off when the battery power is too low for an accurate measurement.
The non-intrusive nature of the HI99551 is particularly attractive in the food industry since it translates itself into substantial savings by leaving products intact, especially those sealed or pre-wrapped. This type of non-intrusive measurement is also useful when the surface temperature is high, for difficult-to-reach places, or hygiene requirements must be followed.
