The Senseca HD320A2 is a dedicated probe for measuring carbon monoxide (CO) concentration in air, designed for use with the Senseca HD32.1 Thermal Comfort data logger.

The probe measures CO concentration in indoor air and, when used together with the HD320B2 CO₂ probe, enables air quality analysis and monitoring in indoor environments, including the detection of carbon monoxide presence or elevated CO levels.

Measurement is performed by means of a two-electrode electrochemical sensor, suitable for determining CO concentration over a measuring range of 0–500 ppm.

The HD320A2 is equipped with a 2 m cable and a SICRAM module, providing compatibility and communication with the measuring instrument.

The probe is supplied factory calibrated and, under normal operating conditions, usually does not require additional adjustment by the user.

For convenient mechanical mounting, the optional HD320AS2 magnetic support can be used to attach the HD320A2 probe to the housing of the HD320B2 probe.

The Senseca HD320A2 is suitable for indoor air quality monitoring, indoor environmental assessment, and CO monitoring applications in combination with the HD32.1 system.
