CTI - DuoSense 4-20 mA CO/NO2 Detector

The Duo-Sense 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 and other audio/visual signaling devices.

Each GG-CO-NO2 sensor comes equipped with an intelligent internal temperature control designed to perform in the harshest of areas. The controlled environment provides optimum moisture control for extended cell life. The high-quality injection-molded polycarbonate enclosure offers excellent chemical corrosion protection and high impact resistance.

The GG-CO-NO2 provides two industry standard linear 4-20 mA output signals compatible with most gas detection systems and PLCs. The output signals 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 parking garages, vehicle maintenance buildings, and other spaces where toxic combustion engine exhaust poses a risk to personnel. The Duo-Sense CO/NO2 sensor detects gas in the concentration ranges for OSHA/NIOSH/ACGIH compliance.

The standard GG-CO-NO2 sensor is designed to work anywhere, and at a lower base-model price than most competing models. Each circuit board is sealed forever in potting compound, protecting electronic components and copper tracing from corrosion.

A specially vented polycarbonate (or stainless steel) enclosure protects the sensor from accidental damage. Each GG-CO-NO2 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.
