DuoSense Modbus vehicle emissions monitor

The DuoSense-M CO/NO2 sensor is equipped with both carbon monoxide and nitrogen dioxide sensing elements to provide accurate readings of toxic levels, with no false alarms. Useful for ventilation activation, alarm notification and audio/visual signaling devices.

The DuoSense-M communicates via Modbus RTU compatible with the MVE Modbus control panel. 4,000 feet per Modbus channel on four channels provides
installation flexibility and large detector capacity.

The CO and NO2 gas sensors are not affected by drastic temperature or humidity variations. Expect an average cell life of 5+years for CO and 2-3 years for NO2 in most applications.

Designed for warehouses, parking garages, and other spaces where toxic combustion engine exhaust poses a risk to personnel.

The DuoSense-M CO/NO2 sensor detects gas in the concentration ranges for OSHA/NIOSH/ACGIH compliance. The standard DuoSense-M sensor is designed to work anywhere, and at a lower base-model price than most competing models.

Each circuit board is sealed in conformal coating, protecting electronic components and copper tracing from corrosion. A specially vented polycarbonate enclosure inside a steel safety cage protects the sensor from accidental damage.

Each DuoSense-M detector monitors a 50’ radius (7,500 square ft). Refer to Uniform Mechanical Code, Uniform Building Code and other authorities having jurisdiction for ventilation requirements, along with audio/visual and other alarm notification requirements.
