The probe is used with Thermal Comfort data loggers HD32.1 and HD32.3TCA for calculating the following indices:

• IREQ – Required insulation
• DLE – Exposure time limit
• RT – Required recovery time
• WCI – Wind Chill Index
• PMV – Predicted Average Rating
• PPD – Dissatisfied percentage
• DR – Draught rate
