Description
The Extech SDL470 light meter is a compact instrument with probes to measure both UVA and UVC and data logging results. UVA is the long waves (365nm) of ultraviolet light while UVC is the short waves (254nm) of ultraviolet light. The SDL470 light meter is ideal for any application seeking to measure these wavelengths.
The Extech SDL470 light meter measures both UVA and UVC over ranges of 2mW/cm2 and 20mW/cm2. The internal data logger date/time stamps and stores files onto an SD card in MS Excel® format to make transferring, storing, and analyzing the data on your PC easier. Readings are shown on a large backlit LCD display. The meter also includes Min/Max and Data Hold functions and auto power off (with disable) to save battery life.
