The HD2102.1 and HD2102.2 are portable instruments with a large LCD display. They measure illuminance, luminance, PAR and irradiance (across VIS-NIR, UVA, UVB, and UVC spectral regions or measurement of irradiance effective according to the UV action curve). The probes are fitted with the SICRAM automatic detection module. In addition to detection, the unit of measurement selection is also automatic. The factory calibration settings are in memory. In addition to instantaneous measurement, the instrument calculates time integral Q(t). Some thresholds can be associated with the integrated measurement and with the integration time, which can be set in the menu. When exceeded these thresholds cause the instrument to stop the integral calculation.
The HD2102.1 and HD2102.2 models are fitted with an RS232C serial port and can transfer the acquired measurements in real time to a PC or to a portable printer.
The HD2102.2 instrument is a datalogger. It stores up to 38,000 samples, which can be transferred from the instrument connected to a PC via the multi-standard RS232C serial port and USB 2.0.
The storing interval, printing, and baud rate can be configured using the menu. Other functions include Max, Min, Avg, REL, HOLD, and automatic power off.
