Introduction
The UVA band is part of the division of ultraviolet wavelengths, known as long-wave dark spot effect ultraviolet light, which is highly penetrating and penetrates the surface layer of the skin, tanning the skin and creating wrinkles. This band is often used in aging experiments to simulate sunlight exposure conditions in natural climates.
The UVA-X1 probe is one of nine models of the LS125 ultraviolet irradiance meter, with a spectral response range of 260nm-400nm, calibrated to a 365nm light source, suitable for aging tests or intensity and energy detection in sunlight.

1. It is suitable for aging test or UV intensity and energy detection in sunlight.
2. The instrument can measure both energy value and power value at the same time.
3. With rich statistical functions, real-time power value, maximum value, minimum value, average value, measurement time, and energy value are displayed at the same time.
4. 3 measurement units can be switched, which are μW/cm2 (default), mW/cm2, W/m2 and different units of data conversion 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:
