Uv Light Intensity Meter

The ls126c germicidal lamp specific uv c light intensity meter is an instrument that can pass the inspection by any national metrology institute in china.

Uv light intensity meter. Because most of the light is at a particular wavelength within the uv bands we won t need to play around with light filters or do any specific tricks to get the light intensity. This meter s sensor is sensitive within a range from 220 to 280nm with maximum sensitivity at 254nm. The uv a meter is a compact rugged easy to operate digital radiometer for measuring and calibrating uv a black light sources used in fluorescent penetrant testing and fluorescent magnetic particle inspections for non destructive testing. J 225 meter measures the intensity of shortwave uv 254nm.

Degradation of curing bulbs lightguides and reflectors can decrease intensity resulting in incomplete cures. Since intensity is the number of photons hitting per unit area you can shine your uv light on a material with desirable band gap and do a photoelectric effect experiment to measure the current. Each meter comes with a sensor attenuation screen and filter. According to chinese national disinfection technical specifications.

Dymax uv radiometers measure the uv a 320 390 nm led 350 450 nm and visible 395 nm to 465 nm light intensity. We can assume that almost all the light is uv c at 254 nm and just add a derating factor of something like 2 5 from the calculated value. 95 uvt should be considered rather ideal. The instrument is equipped with a 1 meter long hook that can be hung directly under the germicidal lamp for measurement.

When using a uv sterilizer with a uv intensity monitor it is very important to ensure that the feed water has a uvt level of at least 75 preferrably higher than 85. In fact the two are simply not separable because of energy power uv light intensity time. Uv transmittance is a measure of the clarity of your water and the ability to pass uv light through it. In the parameter list of many uv energy meters on the market there are not only uv energy measurement range but also uv power uv light intensity measurement range.

Measures uv a light irradiance. Uv light meters are also used to confirm that operators are properly shielded from uv exposure.
