Descriptions
HD32.3TC is a portable instrument indicated for the microclimate and Indoor Air Quality (IAQ) analysis.
Depending on the probes connected, the instrument measures:
- T dry bulb temperature
- Tnw natural ventilation wet bulb temperature
- Tg globe thermometer temperature
- RH relative humidity
- Va air speed
- CO2 carbon dioxide
- Patm atmospheric pressure
- PM1.0, PM2.5, PM10 particulate matter
- VOC index (Volatile Organic Compounds)
and calculates:
- WBGT indoor (Wet Bulb Globe Temperature) index in absence of solar irradiation
- WBGT outdoor (Wet Bulb Globe Temperature) index in presence of solar irradiation
- Mean radiant temperature Tr
- PMV (Predicted Mean Vote) index
- PPD (Predicted Percentage of Dissatisfied) index
- TU (Turbolence) index
- DR (Draft Rate) index
- HI (Heat Index)
- UTCI (Universal Thermal Climate Index)
- TEP (Perceived Equivalent Temperature)
- Estimation of SARS-CoV-2 virus natural decay on surfaces.
Reference standards:
- ISO 7726 Ergonomics of the thermal environment – Instruments for measuring physical quantities.
- ISO 7730 Ergonomics of the thermal environment – Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local
thermal comfort criteria. - ISO 7243 Ergonomics of the thermal environment – Assessment of heat stress using the WBGT (wet bulb globe temperature) index.
- ASHRAE Standard 55 Thermal Environmental Conditions for Human Occupancy.
- ASHRAE Standard 62.1-2019 Ventilation for Acceptable Indoor Air Quality.
- ASHRAE Standard 62.1-2019 Ventilation for Acceptable Indoor Air Quality.
