Light Meter/Datalogger
Extech’s compact UV Light Meter includes two types
of probes: one to measure UVA (long wave 365nm)
and the other to measure UVC (short wave 254nm)
light sources up to 20mW/cm2. The SDL470 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. The unit also has a Type K/J
thermocouple input to capture temperature readings
(temperature probes not included).
