Linshang Launches LS135 Multi-Probe UV Light Meter and Upgraded LS129 UV Digital Probe
#Product Information ·2026-07-15 10:30:44
Linshang has recently introduced two new UV measurement products: the LS135 Multi Probe UV Light Meter and the upgraded LS129 UV Digital Probe. With expanded probe options, practical functions, and straightforward operation, the two products provide more flexible solutions for UV measurement, UV curing, UV sterilization, light source testing, and industrial online monitoring applications.
LS135 UV Light Meter
The LS135 main unit can be connected with 12 different probes, offering a more flexible alternative to the traditional “one meter, one probe” design. With one host and multiple optional probes, users can cover different UV testing scenarios without purchasing several separate meters. This helps improve testing efficiency and reduce equipment costs. The 12 optional probes cover UVA, UVB, UVC, blue light, and other wavebands, making the instrument suitable for a wide range of UV measurement requirements.

UVB+UVC+Blue light band probe
The LS135 UV Light Meter is equipped with a 3.5 inch high definition touch screen, making daily operation clear and intuitive. During measurement, the instrument displays a real time power curve, allowing users to monitor and analyze UV intensity changes across different wavebands. It can measure both power and energy values, and automatically calculate maximum, minimum, average, uniformity, and other key data, reducing the need for manual calculation.
LS135 UV Light Meter Test Interface
At the same time, the upgraded LS129 UV Digital Probe now adds 4 new fiber optic probes to the existing UVALED, UVA, and UVC probe options. These fiber optic probes are designed for high temperature UV LED array sources and high pressure mercury lamps. Straight probes, including UVALED X1 and UVA X1, and right angle probes, including UVALED X2 and UVA X2, are available for different installation and measurement conditions.
LS129 UV Digital Probe
The LS129 UV Digital Probe is equipped with a standard RS485 communication interface and supports the MODBUS protocol. It can be connected to PLCs, HMIs, computers, and other equipment, and also supports multi unit networking. This makes it suitable for online monitoring of UV power and energy in industrial production lines and automated equipment.
