Introduction
In addition to the traditional mercury lamp curing method, there are also LED lamp curing methods in the curing industry. Compared with mercury lamps, LED lamps have the following characteristics: long life, cold light source, no heat radiation, high energy, uniform irradiation, improve production efficiency, do not contain toxic substances, and are safer and more environmentally friendly than traditional light sources.
The UVA LED probe is one of the 9 probes of the LS125 ultraviolet radiometer, with a spectral response range of 340nm-420nm and a peak wavelength of 395nm, which is suitable for intensity and energy detection of LED lamps.

1. The instrument can measure the energy value and power value at the same time.
2. It has rich statistical functions, real-time power value, maximum value, minimum value, average value, measurement time, and energy value are displayed at the same time.
3. It can switch between 3 measurement units, namely mW/cm2 (default), W/cm2, W/m2 data conversion between different units without manual calculation.
LS125 multi-probe ultraviolet irradiance meter, using digital probe, plug-in design, one host can match a variety of probes, the instrument intelligently judges the model of the probe, according to the test of ultraviolet spectrum range, range, size of the measuring hole, application industry, etc., 9 different ultraviolet probes have been developed, each probe selection refers to the following figure:
