Compared with traditional low-pressure mercury lamps, LED germicidal lamps have the characteristics of longer service life, more energy saving and higher efficiency. At present, they have been widely used in disinfection of various small household appliances. Such as: disinfection bags, bottle sterilizers, toothbrush sterilizers, wall breakers, trash cans, etc. In these places where LED germicidal lamps are used, the UVCLED-X0 probe needs to be used to detect the radiation intensity of its ultraviolet light source. For the LED lamp detection using LS125+UVCLED-X0 Probe ,please refer to the following video:

  1. 1. The difference between UVC-X0, UVCWP-X1 and UVCLED-X0 UV probes for LS125 UV light meter host

    UVC-X0 and UVCWP-X1 probes are suitable for detecting 254nm low-pressure mercury germicidal lamps, while UVCLED-X0 is suitable for UVC LED light source; the UVCWP-X1 probe is a waterproof probe with 1m waterproof depth.

  2. 2. Which probe is recommended if I need to measure both 254nm low-pressure mercury lamp and UVC LED light course?

    It is recommended to use the LS125 UV light meter host and UVC-X0, UVCLED-X0 probes.

  3. 3. Whether a traceable calibration certificate is included?

    UVC-X0 and UVCWP-X1 are mainly used to detect 254nm low-pressure mercury germicidal lamps, which 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.

  4. 4. What's the working temperature of the UV probes?

    The 9 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.
