Helping you SEE if you’ve exceeded the daily limit of UV-C exposure

Intellego Technologies is proud to introduce its latest innovation in colorimetric UV indicator technology. The Personal UVC Exposure Indicator is designed for individuals who are working with or in close proximity to UV-C equipment. The yellow indicator will change color when exposed to an accumulated dose of UV-C (254 nm), revealing the word STOP when 6 mJ/cm² of irradiation has been reached.

According to the American Conference of Government Industrial Hygienists (ACGIH), the Threshold Limit Value (TLV) for UV-C is 6 mJ/cm², as indicated in the Documentation of the Threshold Limit Values and Biological Exposure Indices, 8th Edition, Copyright 2020.
