Introduction
UVB is known as the ultraviolet rays of the medium-wave erythema effect, which can promote the metabolism of minerals and the formation of vitamin D in the body, and long-term exposure will make the skin tanned, molting and red and swollen, and is used for ultraviolet health care lamps, medical physiotherapy lamps, plant growth lamps, fluorescent lamps, aging experiments, etc.
The UVB probe is a digital probe specializing in detecting UVB light sources, and is one of the 9 probes of LS125 ultraviolet intensity Detector, with a spectral response range of 280nm-320nm, which is suitable for UVB light source measurements of wavelengths such as 297nm, 308, and 313.

1. It is suitable for UVB light source measurement at 297nm, 308nm, 313nm and other wavelengths.
2. The instrument can measure the energy value and power value at the same time.
3. It has rich statistical functions, and the real-time value, maximum value, minimum value, average value, measurement time, and energy value are displayed at the same time.
4. It can switch between 3 measurement units, namely μW/cm2, mW/cm2, W/m2, and 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:
