HD32.3 - 3 - V1.4

1. GENERAL FEATURES

HD32.3 is designed for:

• Analysis of hot environments through WBGT index (Wet Bulb Globe Temperature) in pres-

ence or absence of solar radiation.

• Analysis of moderate environments through PMV index (Predicted Mean Vote) and PPD in-

dex (Predicted Percentage of Dissatisfied).

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.

NOTE: The set acquisition interval is the same for all the probes connected to the instrument.

HD32.3 instrument can contemporarily detect the following sizes:

• Globe thermometer temperature Tg with TP3276.2 TP3275 or probe.

• Wet bulb temperature with natural ventilation Tn with HP3201.2, HP3201 or TP3204S

probe.

• Ambient temperature T with TP3207.2 TP3207 or probe.

• Relative Humidity RH and ambient temperature T with HP3217.2 or HP3217R probe.

• Air speed Va with or AP3203.2 AP3203 probe.

On the basis of the detected measurements, HD32.3 with TP3207.2 (or (or TP3207), HP3276.2

HP3275) and HP3201.2 (or HP3201 / TP3204S) can calculate:

• WBGT(in) index (Wet Bulb Glob Temperature: wet bulb and globe thermometer tempera-

ture) in absence of solar irradiation.

• WBGT(out) index (Wet Bulb Glob Temperature: wet bulb and globe thermometer tempera-

ture) in presence of solar irradiation.

On the basis of the detected measurements, HD32.3 with HP3217.2 (or HP3217R), HP3276.2 (or

HP3275) and AP3203.2 (or AP3203) probes can calculate:

• Medium radiant temperature Tr.

• PMV index (Predicted Mean Vote).

• PPD index (Predicted Percentage of Dissatisfied).
