Advanced light-hazard meter


Gigahertz-Optik’s X1-3 Light Hazard Meter with the XD-45-HUV UV-Hazard Detector, XD-45-HB BLUE-Light Hazard Detector and XD-45-HB-SRT200 FOV & Distance Adapter fulfills the requirement for a handy field-portable meter for product classification and light-hazard assessment. Four-channel technology with an alphanumeric, four-line backlit display allows the X1-3 to operate and read out two separate multi-sensor/filter detectors required to conform to IEC 62471 guidelines for both UV and blue-light hazard assessment.The XD-45-HUV UV-Hazard Detector covers the full ACGIH / ICNIRP UV spectral effectiveness function using two sensor/filter/diffuser combinations providing separate ACGIH UV-A (325 to 400 nm) and ACGIH UVC/B (250 to 325 nm) spectral responses for increased accuracy by reducing spectral mismatch errors. The multiple detector design ensures proper isolation between the ACGIH, UV-A and UV-C/B spectral regions. A third sensor UV-A (315 to 400 nm) is included for assessing eye hazard. http://www.gigahertz-optik.de/164-1-X13+Light+Hazard+Meter.htm
