infrared thermometer(forehead type)

forehead infrared thermometer HT-F03B I. Brief Introduction to the Product HT-F03B infrared thermoscope is a thermoscope that measures the temperature of human body by using the principle of receiving infrared. When using, it is only required to align the detection window with the forehead to measure the body temperature quickly and accurately. II. Basic Operating Principle Any object with its temperature higher than the absolute zero will radiate a certain proportion of infrared energy according to its own temperature. The amount of radiation energy and its distribution by wavelength are closely related to the object’s surface temperature. In accordance with this principle, the surface temperature of forehead can be measured accurately, and the accurate body temperature can be determined and shown by offsetting the difference between the surface temperature of forehead and the actual body temperature. III. Product Features Specially designed for measuring the body temperature, with a dynamic offset for the ambient temperature and body temperature. Exclusively using the Heimann infrared probe for temperature measurement, with a high accuracy of measurement and a more stable performance. Providing the function of sound notification of higher body temperature. Capable of storing 32 sets of measurement data. Backlight LCD digital display. Providing two temperature modes, i.e., Fahrenheit scale and Celsius scale, for selection. Providing the function of auto shutdown to save electric power. Small size, reasonable structure and convenient operation. Selecting the body-temperature measurement mode to measure the temperature of any object with its temperature less than 100ºC and its emissivity equal to 0.95. IV. Main Technical Indicators 1.
