I. IR thermal imager resolution
The mainstream infrared thermal imager resolutions are 384x288 and 640x480, and the higher the resolution, the better. For dry ordinary consumers, it is recommended to choose 384x288.

II. Infrared thermal imager lens
Infrared thermal imager lens for germanium mirror, non-ordinary optical glass lens. Germanium mirror is expensive, is based on the weight of the lens to price, small diameter germanium lens cost thousands of yuan, large diameter germanium lens tens of thousands of yuan.
The lens parameters of the infrared thermal imager are measured in focal length (non-caliber size). In theory, the larger the focal length, the greater the magnification of imaging.

III. Precision of temperature measurement
In the critical period of the epidemic, in addition to the supply capacity, another concern is the measurement accuracy of infrared thermal imaging thermometer.
Long distance, large area and large passenger flow are the advantages of infrared thermal imaging thermometer. As long as it appears in front of the thermal imaging camera, it can be measured within 1 second. At the same time, the computer screen will display everyone's body temperature "color" in real time. The system will automatically notify the staff to deal with it in by acousto-optic alarm. But because of exposure to the environment. In the big crowd,. The measurement accuracy of infrared thermal imaging thermometer will also be affected by many factors.
The infrared thermal imager for human body temperature measurement is an instrument that accurately controls the temperature measurement error to ±0.6℃. Nevertheless, the precision of ZIP Technology’s temperature measurement is ±℃0.3

IV. Clarity, brightness, contrast adjustment
In order to satisfy the use of infrared thermal imager in various environments, the infrared thermal imager must have the adjustment of these three parameters. But these three parameter adjustment, to the detector performance, the hardware design and the software design request is high, needs the relatively strong research and development ability. Therefore, some non-professional infrared thermal imager on the market does not have these three functions, or some functions between the three.

V. Temperature alarm
Area alarm range can be set to alarm and record people with higher temperature, but not other high temperature objects, such as cigarette butts and food. It can realize accurate single point & multi-target high temperature automatic marking alarm, and can set up multiple isolation areas to effectively prevent error alarm and other interference.

VI. Type, size and resolution of built-in screen for hand-held infrared thermal imager
The effect of the built-in screen directly affects the observation effect. Built-in screens are tiny screens, magnified by the eyepiece of the infrared thermal imager.
1. hand-held infrared thermal imager to ensure the observation effect, professional thermal imager recommends the use of imported LCOS or OLED screens, traditional LCD screens, will affect the image effect.
2. the higher the resolution of the built-in screen, the better, the built-in screen resolution of the professional thermal imager can reach 1280/720, but in order to save costs, many brands use 640x480, or even 320x240 resolution screens.
3. the size of the built-in screen, try to use 0.35 inch screen, too small inner screen, such as 0.20 screen, need eyepiece higher magnification, too high magnification eyepiece will affect the image observation effect.

We ZIP technology strictly according to the above points, to create the best quality hand-held infrared human body thermal imager, for more and more units to resume production, restore on-site office, travel to work to do the first level! !
