Hanna Instruments HI99551-00 Infra red thermometer



  • Non-invasive measurement
  • HOLD function
  • Battery life indicator on startup


The HI 99551 thermometer employs infrared technology to measure surface temperatures. Infrared readings are extremely fast with a response time typically around 1 second.

One big advantage of this meter is the non-intrusive nature of measurements. This feature is particularly attractive for food distribution, retailing and markets since it translates practicality into savings by leaving products intact, especially those sealed or pre-wrapped.

In order to measure the temperature, simply turn on the meter and point to the product or target. Readings are displayed on the LCD. This type of non-intrusive measurement is also useful when the surface temperature is too high to approach, for difficult to reach places or for hygiene requirements.

If you must check the core temperature in addition to surface measurement, the
HI 99556 is the ideal solution for you. Simply attach an optional external probe to the meter and you have a 2-in-1 infrared-thermistor thermometer.

A HOLD function freezes the display to allow the user time to record readings.
