Short-/Long-wave UV Irradiance Light Meter with Datalogging

The SDL470 is a UVA/UVC Light Meter and Data logger. The SDL470 can measure both long wave and short wave UV irradiance under UVA and UVC light sources respectively. This meter features a cosine correction filter, data logging to Excel format, offset adjustment for relative measurements, type K/J thermocouple input for temperature measurements (probe sold separately), record/recall modes, min and max readings, data hold plus auto power off with disable function.

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).
