Infrared Thermometer for the Food Industry - HI99550

The HI99550 is an infrared thermometer designed to measure surface temperatures for the food industry. With a quick, one-second response time and battery life indicator, this thermometer is an ideal solution for non-intrusive infrared measurements

Features at-a-glance

°C Readout - Measurements are displayed in degrees Celsius on the clear, easy to read LCD display.

Optic Coefficient - The optic coefficient is the distance between the sensor and the measured object is an important factor in infrared measurement. With a 3:1 relationship between the distance and object area, the HI99550 can measure an area with a diameter that is one third of the distance between the sensor and the object.

Fixed Emissivity - Emissivity is the ratio of infrared radiation emitted by an object to that emitted by a perfect black body at the same temperature. The HI99550 was designed to measure the temperature of objects with an emissivity of 0.95, which is characteristic of most objects and surfaces being measured.

Low Battery Indicator - When the battery level is below 10%, a warning symbol will blink to indicate low battery condition.
