When it comes to UVC254 UV radiometer, the most common one is the detection of low-pressure mercury lamps (traditional germicidal lamps). But in fact, with the rise of new UVC LED light sources and the application of short-wave UVC band in different industries, when selecting the UVC254 UV radiometer, it should also be selected according to the type of light source. There are several common types:
1.UVC254 UV radiometer applied to hospital UVC germicidal lamp detection
The germicidal lamp used in hospitals is generally a low-voltage mercury lamp with a 253.7 nm ultraviolet light source, commonly known as 254 nm. For the detection of such a light source, a short-wave UV radiometer with a peak wavelength of 254 nm is required. Because the short-wave ultraviolet 254nm has certain damage to the human body and the hospital has a large number of germicidal lamps, the hospital should consider the protection of the human body and the convenience of multiple lamp detection when selecting the instrument. Here we recommend a UVC254 UV radiometer that does not require any protective equipment, which is the LS126C UV radiometer produced by Linshang Technology. This instrument has real-time monitoring function of mobile APP and can store up to 25 sets of test data, which can record the test time of each tube and the luminous power graph of each tube.
2.UVC254 UV radiometer applied to water treatment germicidal lamp detection
The germicidal lamps used in the water treatment industry are generally high-power UVC254 lamps and the tubes are placed in the water for a long time. For UV detection in this case, use a UVC254 UV radiometer that is waterproof and the power range is large enough. Linshang Technology has a high-power UVC-WP probe that can be waterproofed. This probe is water resistant to one meter deep and has a maximum power range of up to 200,000 μW/cm2. It can meet the strength testing requirements of water treatment germicidal lamps.
3.UVC254 UV radiometer applied to UVC LED germicidal lamp detection
The rise of UVC LED light sources also promoted the birth of UVC254, a UV radiometer for UVC LED germicidal lamps. At present, the more commonly used UVC LED ultraviolet light sources mainly have several bands of 265 nm, 275 nm and 280 nm. Since the spectrum of the UVC LED source is different from the spectrum of the low-pressure mercury lamp 254 nm, the conventional UVC254 UV radiometer can not meet the testing requirements of the various bands of the UVC LED. For the detection of UVC LED germicidal lamps, it is recommended to use the Linshang LS125 host + UVC LED probe, which is a wide-spectrum probe suitable for use from 220nm. The intensity of each short-wavelength UVC band is measured up to 200000μW/cm2.
In summary, the short-wave UVC light source mainly has two kinds of traditional low-pressure mercury lamps and UVC LED light sources and each of the light sources has high power and low power. Therefore, when selecting the UVC254 UV radiometer, it is necessary to choose the suitable UVC 254 UV radiometer according to the type and power of the light source.
