HD32.3TC – HD32.3TCA – Thermal Microclimate PMV-PPD / WBGT

HD32.3TC – HD32.3TCA – Thermal Microclimate PMV-PPD / WBGT

Thermal Comfort Data Logger - PMV/PPD - WBGT and TU Measurement according to ISO 7726, ISO 7730 and ISO 7243

HD32.3 and HD32.3A have exactly the same possibilities. The difference between the 2 codes:

HD32.3TC is the portable version, mostly used in combination with a table stand (small tripod).
HD32.3TCA is the version that is being used with a stable tripod, suitable to be used for measurements during a longer period.
Technically the difference is simple: with the HD32.3A the sensors are being connected by a cable and a black globe of 150mm is used. With the HD32.3 the black globe is 50mm and the sensors are being connected directly on top of the instrument. Both are fully according to the applicable ISO regulations.

HD32.3TC(A) is the next generation in measuring Thermal Comfort, the ultimate portable data logger for the measurement of the microclimate and the analysis of the Indoor Air Quality (IAQ).

HD32.3TC(A) measure simultaneously:

  • dry bulb temperature;
  • natural ventilation wet bulb temperature;
  • globe thermometer temperature;
  • relative humidty;
  • air speed

A bright and clear touch display allows the calculated values for WBGT, PMV/PPD and TU to be directly visible. The data are immediately available via “cloud” application accessible remotely via Wi-Fi connection. The data logger has a large memory capacity for long lasting measurement cycles. Moreover, the rechargeable battery guarantees a working autonomy of at least 24 hours.

With intergrated voice recording and camera to include voice and visual comment during the measurments in order to be able to identify quickly and easily the specific measuring places.

Reference standard:
