LS138 UV Energy Meter
UVA/UVB/UVC/UVV simultaneous measurement
Simultaneously tests UVA, UVB, UVC, and UVV energy and intensity
Monitor temperature and UV power in real time
2048 times/second sampling for accurate measurement
Includes PC software for easy report export and printing
The UV energy meter simultaneously measures UV energy, intensity, temperature, and irradiation duration across four bands (UVA/UVB/UVC/UVV). It's suitable for UV intensity testing in applications such as curing machines, dryers, coating machines, exposure units, and printing equipment. It also supports detection for UV energy, intensity, and temperature in light sources like mercury, halogen, gallium, iron, and xenon lamps.

Features
Simultaneously measure UVA, UVB, UVC, and UVV
The intelligent UV energy meter automatically identifies the test wavelength range and simultaneously measures UV power and energy across UVA, UVB, UVC, and UVV. It allows users to monitor surface curing (UVC) and penetration curing (UVA/UVV) wavelengths, optimizing the curing process and enhancing product performance and production efficiency.
Large LCD display
The instrument features a large LCD screen to monitor temperature and UV power in real time, displaying test curves with clear maximum and minimum values.
Ultra-high-speed data acquisition
High-speed acquisition, 2048 samples per second, can accurately calculate UV energy.
High temperature resistant design
High-precision fast-response temperature probe that dynamically measures the actual temperature in the curing machine.
High-precision temperature detector
High-precision fast-response temperature probe that dynamically measures the actual temperature in the curing machine.
Built-in timer
The length of UV curing time can be accurately recorded to ensure that the process is carried out according to the set time, which is convenient for subsequent quality tracking and review.
Quality assured, pass authoritative metrology inspection
Professional-grade UV energy meter, which can accurately analyze various types of UV radiation and ensure passing the inspection of the national authoritative metrology institute.
Provide powerful PC software
The instrument adopts Type-C interface, supports computer software to read detailed record data, generate data curves and print out test reports.
Two measurement modes
Automatic measurement mode and manual measurement mode can be switched, suitable for a variety of detection environments.
Auto Measurement Mode
The auto measurement mode accurately records curing time and displays the corresponding light intensity curve.
Manual Measurement Mode
When multiple light sources are used, the overall distribution of the UV light source can be analyzed through the power curve.Multiple functions can be set
Users can freely adjust measurement bands, units, smoothing, and other settings to meet diverse needs.
230-445nm full-band UV measurement
Built-in large-capacity memory, can record up to 60,000 power data and 3,800 temperature data
The last test data is automatically displayed after power-on, so there is no need to worry about data loss
