Air Quality Sensors

• Field-selectable 4-20mA, 0-5VDC and 0-10VDC outputs for operation flexibility
• Integrated transducer and probe - eliminates the need to install a separate pick-up tube
• Non-dispersive infrared technology (NDIR) repeatable to ±20 ppm ±1% of measured value
• Automatic Baseline Calibration (ABC) maintains sensor accuracy
• Humidity and temperature sensor options available

Schneider Electric’s Plant Room CO₂ sensors maximize energy savings, while helping optimize ventilation. These sensors allow ventilation systems to be controlled by the amount of CO₂ present in a space. The SCD Series detect fluctuations in CO₂ levels and signal ventilation systems to provide an inlet of fresh air optimal for the space at a given time saving energy and increasing tenant comfort.

• Controlling ventilation in response to occupancy
• Office buildings, hospitals, industrial facilities, schools, retail stores, etc.
• ASHRAE 62.1 air quality standard compliance
