Cubic Duct Mount Transmitter AM6208D monitors the indoor environment CO2 concentration accurately and is used for demand control ventilation, to help reduce energy waste and consumption. With analog signal outputs, it is used in evaluating the necessity of ventilation and it is the foundation of a complete ventilation control system. With ABC (Automatic Baseline Correction) function, Cubic duct-mounted CO2 sensor will keep tracking the lowest reading during the ABC cycle and will realize automatic calibration. Therefore, the duct mounted carbon dioxide transmitter can stay with long-term good and stable performance.
Used for CO2-based ventilation control.
Reliable non-dispersion infrared (NDIR) technology for CO2 sensing
High accuracy, in conformity with RESET Standard Grade A & California Title 24
Flexible industrial standard analog output: 0-10 VDC, 4-20mA
Optimized auto baseline correction, maintenance-free
OEM/ODM available (sensor configuration, appearance design, PCBA design, output signal, communication protocol etc.)
