Measuring Ultraviolet Light
The ultraviolet index or uv index is an international standard measurement of the strength of sunburn producing ultraviolet uv radiation at a particular place and time.
Measuring ultraviolet light. Measuring uv exposure starts with tracking the uv index scale. Measurement of the radiant flux and irradiance of uv leds is a particularly demanding task. Instantly verify that your uvc disinfecting system is getting the job done. Next let s look at the method for detecting uvc light source with ls126c uv lamp intensity meter.
Navigate through the various links to find a brief discussion on the uv cure process and answers to the how s when s and why s of the various techniques and devices used to monitor a uv source and to measure its output. Ls126c uv measurement device as a professional uv lamp intensity meter will be provided with a 1 meter extension hook the customer only needs to stretch the hook to 1 meter and then directly hang the meter on. One of the easiest ways to monitor sun exposure is looking at the daily uv index which is given on the iphone weather app dr. Jelight company also sells and services meters to measure ultraviolet light.
The scale was developed by canadian scientists in 1992 and then adopted and standardized by the un s world health organization and world meteorological organization in 1994. Absolute measurement gives the amount of uv energy on the object per unit area expressed in milliwatts per square meter mw m 2 this is useful to determine the uv dose that an object receives which can help predict its future state i e. How to measure uvgi first an uvc lamp intensity measurement device is necessary. It is primarily used in daily forecasts aimed at.
Measuring the output of ultraviolet light emitting diodes. While taking an absolute measurement the uv meter must be parallel to the object. Measurement of low and medium pressure mercury uv c leds and excimer light sources 240 310 nm. Low radiant flux in particular in uvbs and uvcs necessitates highly sensitive optical measuring systems for precise radiometric characterization.
The sensor was designed to measure relatively low levels of uv light such as sunlight and now they are blasting it with a shedload of radiation so they have to effectively disable one of the. The ilt2400 uvgi is a complete system for measuring uvc germicidal disinfecting light sources such as low and medium pressure mercury lamps and leds.
