Measuring Ultraviolet Light

Measuring uv exposure starts with tracking the uv index scale.

Measuring ultraviolet light. Measurement of low and medium pressure mercury uv c leds and excimer light sources 240 310 nm. Jelight company also sells and services meters to measure ultraviolet light. Jelight company also offers different types of probes that can be purchased separately to meet your specific measuring application. It is primarily used in daily forecasts aimed at.

Instantly verify that your uvc disinfecting system is getting the job done. 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. 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. 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.

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. Measurement of the radiant flux and irradiance of uv leds is a particularly demanding task. Measuring the output of ultraviolet light emitting diodes. Low radiant flux in particular in uvbs and uvcs necessitates highly sensitive optical measuring systems for precise radiometric characterization.

Our portable handheld instrument units are battery operated lightweight and easy to use. While taking an absolute measurement the uv meter must be parallel to the object. Next let s look at the method for detecting uvc light source with ls126c uv lamp intensity meter. How to measure uvgi first an uvc lamp intensity measurement device is necessary.

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. 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.
