HI-FOCUS HF-RT105 HI-FOCUS Infrared Thermometer Non Contact Forehead Thermometer with 1-10 cm Range Thermometer  (White)

HI-FOCUS Infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured. They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns, to describe the device's ability to measure temperature from a distance. By knowing the amount of infrared energy emitted by the object and its emissivity, the object's temperature can often be determined within a certain range of its actual temperature. Infrared thermometers are a subset of devices known as "thermal radiation thermometers". •FDA Approved Non Contact Thermometer • Measurement method -Contact less • Measuring distance - 5cm to 10 cm • Measuring range - 32°C ~ 42.9 °C (89.6 °F~109.2 °F) • Accuracy ± 0.3 °C • Response time 0.5 Sec • Unit of measurement-Celsius (°C)/ Fahrenheit (°F) • High Temperature Screen Flashing Alarm •LED Backlight
