With the rapid evolution of science and technology, thermometers have transitioned from traditional oral watches to modern infrared forehead thermometers, significantly enhancing convenience. Equipped with a clear LCD display, the infrared forehead thermometer is lightweight, portable, reduces measurement time, and enhances overall hygiene and safety. Zhengzhou Haorunqijin’s brand of infrared forehead thermometer, featuring voice broadcast, offers a humane touch. This instrument swiftly broadcasts the measured temperature, taking only 1 second, ensuring precise measurements with an error margin within ±0.2 degrees. Suitable for family use due to its forehead contact feature, it proves highly practical.
Classification of Infrared Thermometers
Infrared thermometers are broadly categorized into contact and non-contact types.
Contact Infrared Thermometers: Common examples include ear thermometers, forehead thermometers, and multi-function thermometers. They offer quick and accurate body temperature measurements, particularly effective for monitoring fever in infants. Proper usage involves gently straightening the ear canal, inserting the thermometer, and pressing the measurement button for one second. This method ensures a safe and guaranteed experience, with a replaceable protective rubber cover for shared family use.
Non-contact Infrared Thermometers: Predominantly represented by forehead thermometers, they measure body temperature from a distance. By pointing the probe at the forehead and pressing the measurement button, data is obtained within seconds. Users may initially encounter varied readings due to unfamiliarity, but with practice, the highest recorded value is generally accurate.

- Clean the thermometer surface lightly with alcohol when required.
Is the Infrared Thermometer Accurate?
The measurement error calculation formula is integrated into the central micro-processing system, ensuring accurate readings by detecting ambient temperature changes. When used correctly, non-contact infrared thermometers demonstrate relatively high accuracy.
