    Extech SDL470 UVA UVC 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/cm 2. 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).
