Practical infrared thermometer MT-210 can measure the temperature in the ear and forehead. While a classical glass thermometer and a digital thermometer directly measure the temperature of the human body, in the ear and forehead, the temperature of the body core is measured by infrared radiation of the body. The MT-210 measures temperature in as little as 1 second, ranging from 34 °C to 43° C and the range of objects 0 °C to 93°. The advantage is that it remembers the last 9 measurements, and tracking the measured values is very easy. It allows the measured temperatures to be displayed in °C but also in °F and the measured temperatures are displayed on a large clear LED display. After about 30 seconds of inactivity, the unit automatically turns off.
