HD32.3 is an instrument for the following measurements: analysis of hot environments using WBGT index (Wet Bulb Glob Temperature: wet bulb
temperature and Globe thermometer) in presence or absence of solar radiation.
• Analysis of the moderate warm environments using PMV index (Predicted Mean Vote)
and PPD index (Predicted Percentage of Dissatisfied).
ISO 7243: Hot environments. Estimation of the heat stress on working man, based on
WBGT index (wet bulb globe Thermometer).
ISO 8996: Ergonomics of the thermal environment. Determination of metabolic rate.
ISO 7726: Ergonomics of the thermal environment – Instruments for measuring physical
ISO 7730: Moderate thermal environments. Determination of PMV and PPD index and
specification of the condition for thermal comfort.
The instrument is provided with three inputs for probes with SICRAM module: the SICRAM
module is an interface between the instrument and connected sensor and communicates
the sensor parameters and calibration data to the instrument
