Measurement accuracy: Body Temperature -- outside (35-42) ? ± 0.3 ? / 0.54 ? / (35-42) ? ± 0.2 ? / 0.4 ?; Object Temperature: ± 1.0 ? / 1.8 ?
Measurement range: Body Temperature -- 32 ? to 42.9 ? (89.6 ? to 109.2 ?); Object Temperature -- 0 ? to 100 ? (32 ? to 212 ?)
Product Introduction: This product is composed of high-precision infrared sensor, microprocessor, memory chip, power supply, electro-acoustic component, liquid crystal display and housing. It can quickly and accurately measure human body temperature or object temperature.
Usage rules -- Human Body Measurement: While waiting, point the thermometer probe at the center of the forehead (above the eyebrow center) and keep it vertical, distance 3 ~ 5cm, press the measurement key to display the measured temperature within about 0.5 seconds; While waiting, press the "-" button once to switch to the temperature measurement mode. Point the thermometer probe at the object and press the measurement button. The measurement temperature will be displayed in about 0.5 seconds.
Working Principle: This product adopts infrared temperature sensing method to measure temperature display or data output. It displays the temperature of the measured object by measuring the thermal radiation of the forehead or object. Net weight is 122g, and the service life is 5 years.
