Real-Time Monitoring via WeChat Mini Program – Protects Users from UV Exposure
With Bluetooth functionality, users can monitor test data wirelessly through the WeChat mini program, eliminating the need for direct contact with UV radiation during testing.
Includes 1-Meter Test Hook
To meet the standard measurement distance outlined in “WST 367-2012,” the device includes a 1-meter test hook. This allows the meter to be positioned on the base, with the sensor suspended directly below the UV lamp for accurate measurement.
Customizable Auto Shut-Off – No Need for Constant Supervision
The auto shut-off feature can be set anywhere between 1 and 255 minutes. Test data is automatically saved upon shut-off, and when the device is turned back on, the screen displays the most recent test result as "Record 1." The meter can store up to 70 sets of data, supporting unattended measurement.
High-Precision UV Sensor with UVC Filter
Equipped with a high-precision UVC filter and a professional-grade sensor, the device ensures that UVA and UVB light do not affect measurement accuracy.
Advanced Digital Probe Technology
With onboard digital signal processing, the advanced probe delivers accurate readings and strong interference resistance.
Smart Data Statistics
The 86127C automatically records real-time values, maximum, minimum, and average readings, as well as measurement duration. When the energy display mode is enabled, it also calculates cumulative energy exposure.
Comprehensive PC Software Support
The device includes a USB interface and dedicated PC software, supporting data transfer and report generation.
Qualifications and Standards
" WST 367-2012 Regulation of disinfection technique in healthcare settings " A.3 Monitoring of the Effect of Ultraviolet Disinfection
UV light meter measurement method
After turning on the UV lamp for 5min, place the UV light meter probe with a measuring wavelength of 254nm at the center of 1m vertical distance under the tested UV lamp. The special UV lamp is measured at the recommended distance. After the meter is stable, the displayed value is the irradiance value of the ultraviolet lamp.
Judgment of results
For ordinary 30W straight tube UV lamps, the irradiation intensity of the new lamp should meet the requirements of GB 19258; the use of ultraviolet lamp irradiation intensity ≥70μW / cm² is qualified; the 30W high-intensity ultraviolet lamp irradiation intensity ≥180μW / cm² is qualified.
WeChat mini program
UV Light Meter supports WeChat mini program. Use your WeChat to scan the QR code below, follow the prompts to use the WeChat mini program. (The mini program only supports Chinese)

FAQ
-
1. Can 86127C UV light meter measure UV dose (energy) ?
The 86127C UV light meter can detect the UV radiation intensity and UV dosage (Energy).
-
2. The difference between 86126C and 86127C and 86125+UVC-X0 UV light meter
1) The radiation intensity measurement range of 86126C is 0-2000μW/cm2, and the radiation intensity measurement range of 86125+UVC-X0 is 0-200000μW/cm2;
2) 86126C is equipped with a 1-meter test hook, which can be connected to the WeChat mini program via Bluetooth and the radiation intensity of the germicidal lamp can be monitored in real time through the WeChat mini program. 86126C can also be connected to PC software to export test data and print reports. 86125+UVC-X0 UV light meter doesn't have the functions described above.
3) 86127C is a professional instrument for measuring the radiation intensity of UVC germicidal lamps. It adopts an integrated design and is easy to operate. 86127C can be set to automatically shut down within 1-255 minutes, and can record up to 9 groups of data.
-
3. Can 86127C UV light meter measure the wavelength of germicidal lamps?
No, the 86127C UV light meter can only measure the UV radiation intensity of the germicidal lamp, and cannot measure the wavelength. If you need to measure the wavelength, you need to use more professional equipment,such as spectrometer.
-
4. Two ways to determine whether it is a 254nm germicidal lamp.
1) Although the spectral response range of 86126C or 86127C or UVC probe is 230-280nm, the measured peak wavelength is 254nm, and the response at other wavelengths is very weak. The low-pressure mercury lamp currently known only has a peak wavelength at 254nm, if the test data is very low, the germicidal lamp peak wavelength may not be 254nm or it's unqualified.
2) Use a spectrometer to measure the spectrum of the germicidal lamp.
-
5. Whether a traceable calibration certificate is included?
The 86127C UV light meter can be ensured to pass the inspection of the Chinese Authoritative Metrology Institute and obtains the calibration certificate (approved by CNAS and ilac-MRA), but the cost of the calibration certificate needs to be paid separately, and the cost is about US $290 (UV intensity and UV dosage inspection).
