The probe measures the carbon monoxide concentration in air. Together with the HD320B2 probe, the HD320A2 probe allows analyzing and monitoring the air quality in internal environments and detecting any loss of CO.
The sensor for the measurement of CO consists of an electrochemical cell with two electrodes.

Measuring range 0 ÷ 500 ppm.

Cable length 2m equipped with SICRAM module.

The probe is calibrated by the company and, usually, doesn’t request any intervention by the user.

A magnetic support (HD320AS2) can be used for fixing the probe HD320A2 to the housing of probe HD320B2.

The post HD320A2 – CO Carbon Monoxide Probe appeared first on Senseca.

The probe measures the carbon dioxide concentration in air. It’s indicated for checking and monitoring the indoor air quality. Typical applications are the check of the air quality in all the buildings where there is a crowd of people (schools, hospitals, auditoria, canteens, etc.), in the working places to optimize the comfort. CO₂ measurement is obtained with an infrared special sensor (NDIR technology: Non-Dispersive Infrared Technology) that, thanks to the use of a double filter and a special measurement technique, warranties precise, stable and long-term measurements. The air to check is spread inside the measurement chamber through the protection membrane placed at the top of the probe.

Measuring range 0 ÷ 5000 ppm. Cable length 2m equipped with SICRAM module.

The probe is calibrated by the company and usually doesn’t request any intervention by the user.
