GENERAL DESCRIPTION

HI 99551 and HI 99556 thermometers employ infrared technol-
ogy to measure the surface temperature.
Infrared measurements are extremely practical with a fast re-
sponse time, typically around 1 second.
Another main advantage is the non-intrusive nature of the
measurement, which is particularly attractive in the food indus-
try 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 due to hy-
giene requirements.
Simply point to the product or the spot and hold down the
measurement key. The measured value will be immediately dis-
played on the LCD.
If in addition to surface measurement, you must check the core
temperature too, then HI 99556 is the ideal solution: simply
attach the external probe to the meter and you will have a 2-in-
1 infrared-thermistor thermometer.
Different models are available, with different temperature ranges.
