The detector head UV-3718 is designed for narrow band UV-C 254 nm radiation sources with distinct 254 nm Peak Emission spectrum.

Ultraviolet light at the 254 nm wavelength is passed through a quartz cell containing the sample water. The intensity of the attenuated light is measured with a sensor and divided by a pure water measurement before a logarithm is calculated. The measurement is reported as absorbance per path length (abs/cm).

Samples of wastewater are compared against a sample of distilled water set to 10 Many UV instruments, like the DR 6000 Spectrophotometer and online UVAS plus sc probe from Hach Lange, offer two methods using the UV/254 nm wavelength for measuring organic constituents in a water sample: UV transmission (UVT) and UV absorbance (A 254). At first glance, the methods appear to be complementary to each other. Two hundred twenty-two nanometres ultraviolet (UV) light produced by a krypton-chlorine excimer lamp is harmful to bacterial cells but not skin. However, the effects of 222-nm UV light exposure to the eye are not fully known.

Since 254 nm UVC harms exposed human tissues, it can only be used to sanitize empty rooms. But 222 nm UVC can be a promising disinfection system for occupied public spaces including hospitals where Yes. It is very dangerous. Fortunately it does not travel well through air and the “power” is reduced the further away you get from the source.
