Measuring range: air speed 0.02 ÷ 5 m/s, temperature 0…+80 °C. Probe stem Ø 8 mm, length 230 mm. Cable length 2 metres. Equipped with SICRAM module.

In combination with the data loggers HD32.1 and HD32.3TCA, the probe is used for calculating the following indices:

• PMV – Predicted Average Rating
• PPD – Dissatisfied percentage
• TU – Turbulence
• DR – Draught rate

The probe is also used for calculating Mean radiant temperature.

On request air speed ISO 17025 calibration certificate 0.15 – 5 m/s.

The kit is composed of instrument, four AA 1.5 V batteries, instruction manual. The probes and cables have to be ordered separately.

The probes necessary for WBGT measurement are the following:

• Dry bulb temperature probes TP3207.2.
• Globe temperature probe TP3276.2.
• Natural ventilation wet bulb temperature probe HP3201.2.

The probes necessary for PMV and PPD measurement are the following:

• Relative humidity and temperature combined probe HP3217.2.
• Omnidirectional hotwire probe AP3203.2.
• Globe temperature probe TP3276.2.

Measuring range: air speed 0.02 ÷ 5 m/s, temperature 0 ÷ +80 °C. Probe stem Ø 8 mm, length 230 mm.

Used with the thermal comfort data loggers HD32.3TC, the probe is used for calculating the following indices:

• PMV – Predicted Average Rating
• PPD – Dissatisfied percentage
• TU – Turbulence
• DR – Draught rate

The probe is also used for calculating Mean radiant temperature.

On request air speed ISO 17025 calibration certificate 0.15 – 5 m/s.

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 HD32.3TCA the sensors are being connected by a cable and a black globe of 150mm is used. With the HD32.3TC the black globe is 50mm and the sensors are being connected directly on top of the instrument.

Both are fully according to the applicable ISO7730, ISO7726 and ISO7243 regulations.

• T dry bulb temperature
• T_nw natural ventilation wet bulb temperature
• T_g globe thermometer temperature
• UR relative humidity
• V_a air speed
• CO₂ carbon dioxide
• P_atm atmospheric pressure
• PM1.0, PM2.5, PM10 particulate matter

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.

The HD32.3TC and HD32.3TCA have additional possibilities compared to the HD32.3 and HD32.3A instruments – sale, repair and maintenance for the old series will of course stay available.
