Delta Ohm HD32.2 / HD32.2A Thermal Microclimate Data Logger – WBGT Index

 

HD32.2/ HD32.2A is a thermal microclimate data logger to measure WBGT (Wet Bulb Globe thermometer temperature) Index in Hot Environments according to ISO 7726 and ISO 7243.

 

WBGT (Wet Bulb Globe Temperature – Wet bulb temperature and globe thermometer) is one of the indices used to determinate the occupational heat exposure. It represents the value, with reference to the metabolic waste connected to a special job, over which the being is in a thermal stress condition. WBGT index combines the temperature measurement of Wet bulb with natural ven­tilation Tn and globe thermometer Tg and, and in presence of solar irradiation with air tem­perature Ta.

 

Description

Product Details

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. Three inputs for Probes with SICRAM module. Probes and cables to be ordered separately. Graphic display. Includes DeltaLog 10 software (downloadable), four AA 1.5 V batteries, instruction manual.

 

The instrument measures (with optional probe):

  • Tn Natural ventilation wet bulb temperature
  • Tg Globe thermometer temperature
  • T Dry bulb temperature (Ambient air)

 

Calculates and displays (probe dependent):

  • WBGT indoor index (Wet Bulb Globe Temperature: wet bulb and globe thermometer temperature) in presence or absence of solar irradiation.
  • WBGT outdoor index (Wet Bulb Globe Temperature: wet bulb and globe thermometer temperature) in presence of solar irradiation.

 

In compliance with: ISO 7726 and ISO 7243
