The HD2102.1 & HD2102.2 are portable instruments with a large LCD display. They measure illuminance, luminance, PAR & irradiance (across VIS-NIR, UVA, UVB & 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 already memorized inside the instruments. In addition to instantaneous measurement the instruments calculate the acquired measurements time integral Q(t). Some thresholds can be associated with the integrated measurement & with the integration time, which can be set in the menu. When exceeded these thresholds cause the instrument to stop the integral calculation. The HD2102.2 instrument is a data logger . 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 & USB 2.0. The storing interval, printing & baud rate can be configured using the menu.
The HD2102.1 & HD2102.2 models are fitted with an RS 232C serial port & can transfer the acquired measurements in real time to a PC or to a portable printer. The Max, Min& Avg function calculate the maximum, minimum or average values. Other function include: the relative measurement REL, the HOLD function & the automatic turning off that can also be disabled.
