Delta Ohm HD32.3TC / HD32.3TCA Thermal Microclimate Data Logger – PMV-PPD / WBGT / TU

 

HD32.3TC and HD32.3TCA are the next generation instruments in measuring Thermal Comfort, and the ultimate portable data loggers for microclimate measurements and the analysis of Indoor Air Quality (IAQ). It measures and calculates WGT, PMV (Predicted Mean Vote), PPD (Predicted Percentage Dissatisfied) and TU (Local Turbulenece intensity) indices.

 

Thermal Microclimate refers to the environmental parameters that influence the thermal exchanges between an individual and the environment in confined places, and that determine “thermal well-being”. The micro-environmental climatic factors, together with the type of work done, condition the worker in a series of biologic responses linked to well-being situations (Comfort) or thermal uneasiness (Discomfort).

 

Description

Product Details

HD32.3TC and HD32.3TCA have exactly the same possibilities. HD32.3TC is the portable version, mostly used in combination with a table stand (small tripod). HD32.3TCA with a stable tripod suitable to be used for long term monitoring. Three inputs for Probes with SICRAM module. Probes and cables to be ordered separately. Includes DeltaLog 10 software (downloadable), 6000 mAh Li-ion battery, USB cable, power supply, instruction manual.

 

The instrument measures (with optional probe):

  • T Dry bulb temperature (Ambient air)
  • Tn Natural ventilation wet bulb temperature
  • Tg Globe thermometer temperature
  • RH Relative humidity
  • Va Air speed
  • CO2, Patm Atmospheric pressure, PMs Particulate matter (to be released)

 

Calculates and displays (probe dependent):

  • WBGT indoor Wet Bulb Globe Temperature index in absence of solar irradiation
  • WBGT outdoor Wet Bulb Globe Temperature index in presence of solar irradiation
  • Tr Mean radiant temperature
  • PMV Predicted Mean Vote index
  • PPD  Predicted Percentage of Dissatisfied) index
  • TU Turbulence index
  • DR Draft Rate index

 

In compliance with: ISO 7726, ISO 7730- Measurement of turbulence, ISO 7730- Measurement of PMV /PPD, ISO 7243- Measurement of WBGT

Features

  • Backlit Color 4” graphic LCD display with capacitative touch
