This non-contact thermometer is extremely accurate and easily portable, very suitable for measuring human body temperature. It is especially good for babies and children, to avoid the torture of classic thermometers. Practical: Designed to measure the forehead temperature of the human body, while the ambient temperature and the forehead temperature are dynamically compensated. High temperature alarm: This product turns on an alarm when it measures high temperature. Precise probe: the infrared temperature probe is a guarantee of high measurement accuracy and more stable performance. Non-contact: the temperature can be detected in a short measuring distance, which is more suitable for body temperature measurement. Portability: This product is small in size and light in weight, very convenient to carry.
