The Delta-Ohm HD2102.1 and HD2102.2 are portable photo radiometers. They measure illumination , luminance, PAR (Photosynthetically Active Radiation) and irradiance (across VIS-NIR, UVA, UVB and UVC spectral regions or in the measurement of effective irradiance according to the UV action curve). The unit works with "intelligent" probes using the SICRAM automatic detection system which is chip contaning all the parameters of a given probe including calibration data. When the probe is attached to the meter the meter can read the chip to identify the probe and is instantly ready to proceed with measurements. In addition to spot measurement the instrument can also integrate measurements for a time integral Q(t) over preset thresholds. The HD2102.2 Version includes datalogging. Up to 38,000 samples with single probes and 14,000 with combined probes can be stored in local memory. Data can be transferred from the instrument connected to a PC via the RS232C serial port or USB 2.0 port. The measurment interval, printing, and baud rate are configured with key pad. Both versions of the instrument HD2102.1 and HD2102.2 are fitted with an RS232C serial port and can transfer data in real time to a PC or a printer. The Max , Min and Average functions calculate the maximum, minimum and average values. Other functions include: the relative measurement REL, the HOLD function. The instruments have IP66 protection degree. A large selection of intelligent sensors available for these instruments as detailed below.
