The Universal Thermal Climate Index (UTCI) is a measure of the thermal environment that influences human comfort and health. The HD32.3TC thermal comfort data logger for PMV/PPD/WBGT/turbulence measurement can be configured to measure UTCI, without hardware changes.
Shown below are some photos of HD32.3TC in the UTCI measurement mode.
An earlier post showed WBGT measurement with a combined temperature and humidity probe. With this configuration, the natural wet bulb temperature is calculated.
Shown below is a configuration of the same HD32.3TC instrument with a wet bulb temperature probe. In this case, the wet bulb temperature is directly measured, in compliance to ISO 7243.
HD32.3TC can be configured in various ways for thermal comfort, indoor air quality and microclimate analysis. Please refer to the data sheet of HD32.3TC for more details.
Shown below is an Delta Ohm HD403TS2 omni-directional air speed transmitter for thermal comfort applications. The measurement range is 0-5 m/s and the output type is 4-20 mA (0-10 V option is available).
The probe can be installed with a standard PG9 or PG11 cable gland.
Shown above is a 50 mm diameter globe thermometer, with Class A 4-wire PT100 sensor. The model is Delta Ohm TP876.1.I. An alternative model with 150 mm diameter (TP875.1.I) is also available. Refer to the instrument datasheet for more information.
For the working principle of globe thermometers, please refer to this article.
Shown below are two sets of Delta Ohm HD32.3TC thermal comfort data loggers, with the following features:

With the 3 probes connected (globe thermometer probe, combined temperature & humidity probe, and air speed probe), it is possible to display either PMV/PPD results or WBGT (both indoor and outdoor) results, as shown below:
The instrument can also be configured to measure UCTI (Universal Thermal Climate Index), with the same probe set.
