The recommended method of maintaining Indoor Air Quality (IAQ) is controlling the ambient concentration of carbon dioxide (CO2).  The Brasch carbon dioxide detector is virtually maintenance free.  The dual beam infrared absorption sensor is self-calibrating and provides exceptional accuracy, sensitivity and reduced drift.  The controller displays CO2 concentration in parts per million and controls a set of contacts that can be used to actuate ventilation equipment.  An optional duct mounting kit can be used to mount the unit directly to the return air duct.
