UV Meters Measure

Q: Which UV light meter should I choose: LS125, LS128 or LS138?

A: LS125 is designed for flexible UV testing with interchangeable probes and supports different UV sources and bands. LS128 is mainly designed for UV curing and exposure applications, with UV power, energy and temperature measurement. LS138 is designed for simultaneous four-channel measurement of UVA, UVB, UVC and UVV.
Q: What UV wavelengths can these UV meters measure?

A: The measurement range depends on the model and probe. LS125 supports multiple interchangeable probes for different UV bands and blue light. LS128 is available for UV curing light sources such as mercury lamps and UV LED sources, while LS138 simultaneously measures UVA, UVB, UVC and UVV.
Q: Can the UV meters measure both UV intensity and UV energy?

A: Yes. The series can measure UV power/intensity and UV energy. LS128 additionally supports temperature measurement and power/temperature curves, while LS138 combines UV power, energy, temperature and curing-time monitoring across four UV bands.
Q: Can UV measurement data be recorded and exported?

A: Yes. For process monitoring applications, LS128 supports data storage and USB data export, with PC software for data analysis and test-report printing. LS138 also supports data storage, real-time measurement curves and PC software export.
Q: What applications can these UV light meters be used for?

A:The meters can be used across different UV measurement scenarios, including UV LED testing, UV curing, UV exposure, UV coating, printing, sterilization, UV aging, laboratory testing and industrial UV equipment monitoring. LS125 is suited to flexible multi-source testing, LS128 to curing/exposure process control, and LS138 to multi-band UV monitoring.
Q: Can I Use One Meter to Measure Different UV Wavelengths?

A:Yes, with LS125. Its interchangeable probe design allows users to select different probes according to the UV source and measurement requirement, making it suitable for multiple UV bands and light-source types.
Q: What Is the Difference Between UV Power and UV Energy?

A:UV power/intensity indicates the instantaneous UV output, while UV energy represents the accumulated UV dose over a measurement period. Both parameters are important for evaluating UV curing and other UV processes.
Q: Can It Be Used for UV LED and Traditional UV Lamps?

A:Yes. The series can be configured for different UV sources. LS125 supports different probes for different light sources, while LS128 is available for applications involving mercury lamps and UV LED sources.
Q: Can the UV Meter Be Used for Production Line Quality Control?

A:Yes. These meters can be used to monitor UV output during curing, coating, printing, exposure and other industrial processes, helping production teams verify process consistency and detect changes in UV performance.
