 Product Description

Hanna HI-99556 Infrared Probe Combi Food Thermometer With Probe

The HI99556 is an infrared and contact thermometer designed to measure both surface and core temperatures for the food industry. With an external probe, a quick, one-second infrared response time, a HOLD function, and battery life indicator, this thermometer is an ideal solution for temperature measurements in the food industry.


HI765PW Thermistor Probe - The HI99556-00 is supplied with the HI765PW NTC thermistor probe. The thermometer accepts this external NTC thermistor temperature probe to allow for core measurements in addition to surface measurements. Measurement selection between the external probe and infrared sensor is simple through a dedicated button on the face of the meter.

°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 HI99556 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 HI99556 was designed to measure the temperature of objects with an emissivity of 0.95, which is characteristic of most objects and surfaces being measured.

HOLD Function - The HOLD function freezes the display to allow the user time to record readings when taken in hard to reach places.

Battery Error Prevention System (BEPS) - The Battery Error Prevention System will shut the meter off when the battery power is too low for an accurate measurement.

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