Four Display Interfaces for Comprehensive Data Monitoring
The meter provides four interfaces to monitor and record UV source data:
Max Values Interface: Shows cumulative energy, peak power, and maximum temperature
RT Interface: Records the duration of UV exposure
Temperature and Power Curve Interface: Displays real-time temperature changes and UV intensity variations
All interfaces can be accessed and switched freely.

Broad Spectral Response
Thanks to its wide spectral sensitivity, the device can measure any UV LED light source with a peak wavelength between 365nm and 405nm.
Advanced PC Software
Connect the meter to a PC for data export, test result printing, and detailed report generation.

Integrated Temperature Measurement
Equipped with a fast and precise temperature sensor, it accurately records the real-time temperature inside UV curing machines.
Heat-Resistant Design
Built with a heat-insulated layer, the device can operate reliably in environments up to 100°C for extended periods. Learn more: Usage Time of Linshang UV Energy Meter at Various High Temperatures.

FAQ
-
1. The difference between 86120 and 86128 UV energy meters
86120 UV energy meter is mainly used to detect 365nm UV high pressure mercury lamp, while 86128 UV energy meter is mainly used to detect 365nm, 385nm, 395nm and 405nm UV LED light sources.
-
2. Whether a traceable calibration certificate is included?
86120 and 86136 are professional UV energy meters used to detect 365nm high-pressure mercury 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 ; 86128 and 86137 are UV energy meters that are professionally used to detect UV 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 these two UV LED energy meters, but no calibration certificates can be provided.

3. How to calibrate UV energy meter, how often do I need to calibrate and how much does it cost?
To calibrate the UV energy meter, please send the instrument back to the manufacturer. Generally, it is recommended to calibrate it once a year. If the storage environment is good and the frequency of use is not high, the calibration period can also be extended according to user needs. The first calibration is free, and the cost of each subsequent calibration is US $32.
