Indoor air quality work often needs more than one gas value. The HD320 family covers carbon dioxide monitoring with the HD320B2, carbon monoxide monitoring with the HD320A2, and separate magnetic mounting with the HD320AS2 support.
The HD320B2 measures CO2 concentration in air from 0...5000 ppm and is suited to workplaces and buildings with high occupancy, including schools, hospitals, auditoria and canteens. Its NDIR double source infrared sensor uses a double filter and a dedicated measurement technique for stable long-term measurements.
The HD320A2 measures carbon monoxide concentration in air and supports monitoring of internal environments and detection of possible CO loss. Both probes are equipped with SICRAM modules and 2 m cables. The HD320AS2 is ordered separately and fixes the HD320A2 CO probe to the HD320B2 CO2 probe housing.
The HD320B2 uses NDIR technology with a double source infrared sensor, double filter and dedicated measurement technique.
The HD320A2 measures carbon monoxide concentration in air with an electrochemical sensor equipped with two electrodes.
The HD320A2 and HD320B2 probes are complete with SICRAM modules and 2 m cables.
The HD320B2 can be recalibrated at 400 ppm in clean air or at 0 ppm using a nitrogen cylinder.
HD320AS2 is a magnetic support for fixing the HD320A2 probe to the housing of the HD320B2 probe.
