Delta OHM HD320B2 - Co2 Carbon Dioxide Probe

HD320B2  is a probe to be used with the HD32.1 Thermal Comfort data logger.

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.
