The UVA/UVC light meter/data logger comes with a UVA probe for long-wave 365 nm UV irradiance measurements and a UVC probe for short-wave 254 nm UV irradiance measurements. The UV sensors are housed in a metal casing and feature a cosine correction filter as well as a data logging function that records measurement data with a date and time stamp on an SD card in Excel format. The device offers an offset setting that can be used for the zero function or for relative measurements. The data sampling rate is adjustable from 1 to 3600 seconds. Additionally, the device has a large illuminated LCD display and a Type K/J thermocouple input for temperature measurements (probes sold separately). The product provides Record/Recall, Min/Max readings, Data Hold, and Auto Power Off with a lock function, and can manually store and recall up to 99 measurement values.
