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

he 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.

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.

Multiple functions can be set

Users can freely adjust measurement bands, units, smoothing, and other settings to meet diverse needs.
