Portable handheld luxmeter data logger for measuring illuminance, luminance, PAR, irradiance (across VIS-NIR, UVA, UVB and UVC spectral regions or measurement of irradiance effective according to the UV action curve). In addition to instantaneous measurement the instruments calculate the acquired measurements time integral Q(t). It stores up to 38,000 samples with a one-channel probe and up to 14,000 samples with combined probes. These data can be transferred from the instrument to a PC via the connection of the multi-standard RS232C serial port and USB 2.0. Storing interval, printing and baud rate can be configured by using the menu. Storage of maximum, minimum, average value and the integral Q(t), RS232 C output for data transfer in real time to a PC or printer. Functions: REL, HOLD and auto power off which can be disabled, IP 67 protection degree. LP471.. series probes with SICRAM module are suitable. The probes and cables for data download have to be ordered separately.
