Shown below is a handheld instrument for CO2 and VOC index measurement, in addition to temperature, humidity, barometric pressure, and air speed measurement.
The meter is HD32.3TC thermal comfort data logger for microclimate index and indoor air quality (IAQ) measurement. There are two probes in the system:
- Left: HP3217BV4 probe for CO2, VOC index, temperature, relative humidity, and barometric pressure measurement
- Middle: AP3203.2 probe for omnidirectional air speed measurement
The HD32.3TC can be used for other applications, as described in other posts:
