Three operating programs are uploaded on the instrument and they can be used according to the analysis:
HD32.1 A operating program: Analysis of the Microclimate in moderate, hot and cold environments.
HD32.1 B operating program: Analysis of Discomfort in moderate environments.
HD32.1 C operating program: Measurement of Physical Quantities for general purposes.
The HD32.1 together with C operating program turns into a multifunction datalogger instrument displaying
maximum, minimum and average values.
By connecting SICRAM probes, the instrument allows measuring temperature, temperature and relative
humidity, air velocity, flow, light (with photometric/radiometric probes).
Thanks to specific software: Moderate Environments, Hot environments, Cold environments and Discomfort, as well as specific probes, the instrument can perform the following measurements:
• Globe temperature
• Natural wet bulb temperature
• Ambient temperature
• Atmospheric pressure
• Relative Humidity
• Air velocity
• Air temperature at the height of the head (1,7m subject standing; 1,1m subject sitting).
• Air temperature at the height of the abdomen (1,1 m subject standing; 0,6m subject sitting).
• Air temperature at the height of the ankles (0,1 m).
• Temperature at the floor level.
• Net radiation temperature.
• Net radiation.
• Radiant temperature asymmetry.
• Illuminance, luminance, PAR, irradiance.
According to measurements performed, HD32.1, together with its software, calculates the following parameters:
• tr : Mean radiant temperature
• PMV : Predicted Mean Vote
• PPD : Predicted Percentage Dissatisfied
• DR : Draught Rating
• tO : Operative temperature
• teq : Equivalent temperature
• WBGTIndoor : Wet bulb Globe temperature
• WBGTOutdoor : Wet bulb Globe temperature in the presence of radiation
• SWp : Sweat rate
• Ep : Predicted evaporative heat flow
• PHS : Tre - Water loss - Dlim tre - Dlimloss50 - Dlimloss95
• IREQ : Required clothing insulation
• DLE : Duration Limit Exposure
• RT : Recovery time
• WCI : Wind chill index
• PDv : Percentage Dissatisfied due to vertical temperature difference (head-ankles)
• PDf : Percentage Dissatisfied due to floor temperature
• PDΔ : Percentage Dissatisfied due to radiant asymmetry
