Huashengchang is located in Shenzhen, is the non-contact infrared human body rapid screening instrument national standard drafting unit, infrared thermometer old brand, but its household infrared thermometer performance mediocre, but industrial infrared measuring instrument is better, with a number of patent achievements.
 
Huashengchang has 3 forehead temperature guns and 1 ear temperature gun, and the appearance and style are relatively old. Due to the large size, the display screen is also larger than the small-sized Citizen thermometer, and it is equipped with backlight and fever warning functions as standard, but there is no light guidance, and it is not convenient to use at night, but it is a good choice in the price range of 100 yuan ~ 150 yuan.
 
The forehead thermometer has a traditional "pistol-style" shape, similar to an industrial thermometer, and the probe is large in size, in contrast to the Citizen that can be wrapped in one hand. The best-selling forehead thermometer DT-8806S has a built-in data memory of up to 32 sets, which is convenient for users to record temperature trends. However, there are only 12 sets of data collected by the ear thermometer, but fortunately, the number of keys is small and the operation is relatively simple.
