PRODUCT DATASHEET 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/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). Features • UVA probe captures long-wave 365nm UV irradiance • Type K/J Thermocouple input for temperature measurements (probes sold separately) measurements under a UVA (black light) source UVC probe captures short-wave 254nm UV irradiance • Large backlit LCD display measurements under a UVC light source • Record/Recall MIN, MAX readings • Cosine correction filter and metal housing • Data Hold plus Auto power off with disable function • Offset adjustment used for zero function or to make • Complete with built-in tilt stand, SD memory card, UVA • relative measurements light sensor with protective cover, UVC light sensor, • Adjustable data sampling rate: 1 to 3600 seconds hard case, Universal AC adaptor, and 6 x AA batteries • Memory stores 99 readings manually • Datalogging feature records readings with date and time stamp on an SD card (included) in Excel® format Specifications Range Max Resolution Basic Accuracy UVA Range 2mW/cm2, 20mW/cm2 0.001mW/cm2 ±4% FS UVC Range 2mW/cm2, 20mW/cm2 0.001mW/cm2 ±4% FS Frequency Bandwidth 365nm (UVA); 254nm (UVC) Type K Temperature -148 to 2372°F (-100 to 1300°C) 0.1°F/°C ±(0.4%±1.8°F/1°C) Type J Temperature -148 to 2192°F (-100 to 1200°C) 0.1°F/°C ±(0.4%±1.8°F/1°C) Memory Datalog readings on SD card (included) Dimensions/ Weight 7.2 x 2.9 x 1.9" (182 x 73 x 47.5mm)/ 16.2oz (475g) Ordering SDL470..............
