Suitable for 222nm far UVC germicidal lamps
Spectral response range: 210-250nm
Simultaneous measurement of energy and power values
Range up to 200,000 μW/cm²
Rich statistical functions
The LS125 UV light meter is a smart host that can support 12 different types of probes. Its main function is data display. The UVC-X2 Probe is one of the 12 probes which is equipped with the LS125 UV radiometer host. The spectral response range from 210nm to 250nm and capable of measuring up to 200,000 μW/cm². It is designed for measuring the intensity and energy of 222nm far UVC lamps.
Compared to other UVC lamps, 222nm UVC germicidal lamps are safer for human body, widely used in medical institutions, air purification, water treatment, and other disinfection applications. Examples include air purification sterilizers, medical germicidal lamps, and UV disinfection doors. Portable UV light meter like the LS125 + UVC-X2 probe are necessary to measure the UV irradiance of these 222nm UV light sources.

FAQ
-
1. The difference between UVC-X0, UVCWP-X1 and UVC-X2 UV probe for LS125 UV light meter host
UVC-X0 and UVCWP-X1 probes are suitable for detecting 254nm low-pressure mercury germicidal lamps, UVC-X2 probe is suitable for 222nm UV germicidal lamps. The UVCWP-X1 probe is a waterproof probe with 1m waterproof depth.
-
2. Whether a traceable calibration certificate is included?
UVC-X0 and UVCWP-X1 are mainly used to detect 254nm low-pressure mercury germicidal lamps, and the UVC-X2 probe is suitable for 222nm UV germicidal lamps. All three probes can be ensured to pass the inspection of the Metrology Institute and obtain a calibration certificate (approved by CNAS and ilac-MRA). The cost of the calibration certificate is about US$200 ; but the UVCLED-X0 probe is professionally used to detect UVC LED light sources. There is no unified inspection standard for LED light sources, each light source and UV energy meter manufacturer has their own calibration standards. We can provide the factory calibration reports for UVCLED-X0 probe, but no calibration certificates can be provided.
-
3. What's the working temperature of the UV probes?
The 11 UV probes of the LS125 UV light meter are not heat-resistant. The probe can be used for a long time at 80℃ or lower. If the temperature is higher than 80℃, it is recommended to use UV energy meter for UVA light source detection.
