86126A UV Light Meter
Designed for UV LED Curing Applications
Ultra-compact probe with a minimum width of just 7.2mm
Broad spectral range: 340nm–420nm
High-speed sampling rate: 2048 readings per second
The 86126A UV intensity meter is specifically engineered for measuring the intensity and energy of UVA wavelengths in UV LED light sources, particularly in the 365nm, 375nm, 385nm, 395nm, and 405nm bands. It is widely used in curing and exposure processes. With its broad spectral response from 365nm to 405nm and ultra-narrow probe width of just 7.2mm, it is ideal for taking measurements in confined spaces where standard probes cannot fit.

1. The difference between 86126A and 86125 UV light meters (UVALED-X0 and UVALED-X1 probe)
The functions of the 86126A UV light meter and the 86125 UV light meter host + UVALED-X0 or UVALED-X1 probe are basically the same. The probe width of 86126A is only 7.2mm, and the diameter of the test hole is 3mm, which is suitable for UV light source detection in a narrow space; the test hole diameter of the UVALED-X0 probe is 10mm, which is suitable for the detection of UV LED plane light sources; the test hole diameter of UVALED-X1 probe is 1mm, it's suitable for the detection of UV LED point light sources.
