LS125 Multi-probe UV Light Meter Host

LS125 Multi-probe UV Light Meter Host


I. LS125 UV Light Meter Introduction

LS125 is a smart host that can support 9 different probes. It can intelligently identify different probes. This host is connected to the probe through an aviation plug. The main function of the host is to display the test data. The host equipped with the probe can be used for ultraviolet intensity and energy detection. When using the host, you need to buy the corresponding probe to use with it according to the test needs.

III. LS125 UV Light Meter Application

Ultraviolet light includes UVA band (315nm-420nm), UVB band (280nm-315nm) and UVC band (200nm-280nm). UVA band is mainly used in photocuring, lithographic exposure, ultraviolet light source, integrated circuit lithography and other industries; UVB band UV lamps mainly include physiotherapy lamps in hospitals and health care places, plant growth lamps and UVB fluorescent lamps for reptiles; UVC band also known as short-wave sterilization ultraviolet, ultraviolet germicidal lamps emit UVC short-wave ultraviolet. Ultraviolet germicidal lamps are mainly used for disinfection and sterilization. They are often used in hospitals, transfer windows of drug factories, disease control centers and sewage treatment plants.
      The LS125 handheld UV measurement device is widely used. Many of the above industries require different ultraviolet probes to detect the radiation intensity or energy value. We can select the appropriate probe to use with the host refer to the application of the measured light source, the spectral response range and the probe test aperture.

IV. LS125 UV Light Meter Probe Selection

According to the spectral response range, application, measuring range and test aperture size of the light source, we have introduced 9 different types of probes (probe must be purchased separately). The selection table is as follows:

1. Select according to the spectral response range and application of the light source

6. Data recording: 9 sets of measurement data can be saved. During the measurement, press the “HOLD” to lock the maximum value and the current value during the measurement at the same time. The data will be saved even after the power is turned off. (Except when the battery is removed)

7. Ultra-low power consumption: The instrument is powered by four AAA batteries. The UV measurement device will automatically shut down after 10 minutes without any operation, which can avoid wasting battery power and prolong the service life of the instrument.
