DELTAOHM heat index instrument HD32.3 from Italy: Use WBGT index (wet bulb temperature: wet bulb temperature and bulb thermometer) to analyze the thermal environment in the presence or absence of solar radiation. Use PMV index (predicted average votes) and PPD index (percentage of dissatisfied predictions) to analyze mild warm environments. Italian DELTAOHM heat index meter HD32.3 reference standard: ISO 7243: Thermal environment. Estimate the thermal stress of workers based on the WBGT index (wet bulb thermometer). ISO 8996: Ergonomic considerations for thermal environments. Measurement of metabolic rate. ISO 7726: Ergonomics of thermal environments - Instruments for measuring physical quantities. ISO 7730: Moderate thermal environment. Measurement of PMV and PPD indices and specification of thermal comfort conditions. The instrument is equipped with three probe inputs with SICRAM modules: the SICRAM module is the interface between the instrument and the connected sensors, which can transmit sensor parameters and calibration data to the instrument
