The instrument is provided with three inputs for probes with SICRAM module: the probes have an electric circuit that communicates with the instrument; the sensor calibration data are saved in its permanent memory. All the SICRAM probes can be inserted in one of the inputs: they are automatically recognized when you switch the instrument on.
The main features of the instrument are:

• Logging: acquisition and memorization of data inside the instrument. Memory capacity: 64 different logging sections, with the possibility to set the acquisition interval of the samples. You can set the duration of the memorization and, with auto-start function; it’s possible to set the starting and finishing date and the hour of data memorization.
• The measurement unit of the temperature visualized sizes: °C, °F, °K.
• The system date and hour.
• The visualization of the maximum, minimum and medium statistic parameters and their cancellation.
• The transfer speed of the data through the serial port RS232.

HD32.2 instrument can contemporarily detect the following sizes:

• Globe thermometer temperature Tg.
• Wet bulb with natural ventilation temperature Tn.
• Ambient temperature T.

On the basis of the detected measurements, HD32.2 can calculate:

•  WBGT(in) index (Wet Bulb Glob Temperature: wet bulb and globe thermometer temperature) in presence or absence of solar irradiation.
•  WBGT(out) index (Wet Bulb Glob Temperature: wet bulb and globe thermometer temperature) in presence of solar irradiation.

These probes are requested for the WBGT measurement:

• Dry bulb temperature probe TP3207.2.
• Globe temperature probe TP3276.2.
• Natural ventilated wet bulb temperature probe HP3201.2.

HD32.2 is the portable version, mostly used in combination with a table stand (small tripod). For measurements during a longer period we suggest the version with a stable tripod HD32.3A.

The kit is composed of instrument, four AA 1.5 V batteries, instruction manual. The probes and cables have to be ordered separately.

The probes necessary for WBGT measurement are the following:

• Dry bulb temperature probes TP3207.2.
• Globe temperature probe TP3276.2.
• Natural ventilation wet bulb temperature probe HP3201.2.

The probes necessary for PMV and PPD measurement are the following:

• Relative humidity and temperature combined probe HP3217.2.
• Omnidirectional hotwire probe AP3203.2.
• Globe temperature probe TP3276.2.
