Multi-probe UV Light Tester Application and Usage

I. The birth of multi-probe UV light tester

1. Division of ultraviolet band
   Ultraviolet rays are generally divided into three bands, UVA, UVB and UVC according to different wavelengths. The specific divisions are as follows: UVA wavelength is 320-400 nm, UVB wavelength is 280-320 nm and UVC wavelength is 100-280 nm. Different UV wavelengths and intensities have different applications.

UVA has a high market share. The most important application markets are curing, as well as nail art, ink printing, copiers, printing machines, shadowless adhesive curing, insect trapping and other fields. UVA also has applications in commercial lighting. UVC and UVB are mainly used for disinfection, sterilization, medical light therapy, etc. UVB is mainly used for medical, while UVC is mainly used for sterilization and disinfection.

2. Necessity of measuring the ultraviolet radiation intensity
   The radiation intensity of all the ultraviolet light sources will attenuate with the increase of the using time. The attenuated ultraviolet light source can reach the sterilization effect or curing effect. The irradiation intensity and duration of the UV lamp in use need to be strictly controlled, which requires an UV light tester to detect the intensity of the light UV Light Tester.
3. What is a multi-probe UV light tester?
   UV light tester is also called UV tester, UV light intensity meter, etc. It is an instrument specially used to measure the intensity of ultraviolet radiation. UV light testers can be divided into single-channel and multi-probe UV light testers. So many customers do not understand what single-channel and multi-probe UV irradiators mean? What’s the difference?

In fact, the so-called single-channel UV light tester can only measure the ultraviolet intensity of a fixed wavelength band. It is relatively simple to use. On the contrary, the multi-probe UV light tester can test the ultraviolet of various bands. For example, Linshang LS125 multi-probe UV light tester can be equipped with 9 probes which can test various ultraviolet bands in UVA, UVB and UVC. The customer’s practicality is very strong. If there are multiple ultraviolet light sources, only one host needs to be purchased and then the corresponding probe can be selected.

4. Multi-probe UV light tester principle
   The UV light tester can measure the intensity and energy of the received UV. The principle is to convert the received UV rays into an electrical signal and then into a digital signal. The single-chip microcomputer adjusts and records the collected digital signals and calculates the measured power values.
