Advanced CO Sensors

GS-CMA Series

The GS-CMA Series are carbon monoxide gas detectors. They use an electrochemical sensor to monitor the carbon monoxide level and output a field-selectable 4-20 mA, 0-5 or 0-10 Vdc. The sensing range and output may be scaled to either 100, 150, 300, 400 or 500 ppm via the on-board menu. A front panel LCD is standard to ensure easy setup and operation. It is available in either wall/surface or duct mount congurations. Other standard features include a back light for the LCD, a front panel test switch, status indication and an alarmbuzzer. The test function may also be controlled remotely with a digital input signal. The on-board menu allows local conguration of all device parameters. Optional features include one or two alarm relays and/or RS-485 network communication congured for ModBus protocol.

Duct Air Quality Sensors, Nema 4X

GS-2AQD Series

The GS-2AQD, Indoor Air Quality Sensor uses an advanced MEMS metal oxide semiconductor sensor to detect poor air quality. The sensor reacts quickly to detect a broad range of VOCs such as smoke, cooking odors, bio-effluence, outdoor pollutants and from human activities. The sensor captures all VOC emissions that are completely invisible to CO₂ sensors. The GS-2AQD provides a linear analog signal output of 0-5 or 0-10 Vdc for connection to a building automation system, as an analog stepped output of 0-10 Vdc as well as an adjustable relay output. Optional temperature output is available.

Duct CO₂ Sensors, Nema 4X

GS-2CDD Series

The GS-2CDD Series are duct carbon dioxide gas detectors. These devices provide precision measurement of CO₂ gas. These sensors use a highly accurate and reliable Non-dispersive Infrared (NDIR) sensor combined with state-of-theart digital linearization and temperature-compensated circuitry to monitor duct CO₂ levels. The duct CO₂ transmitter principal of operation is based on the Venturi effect of the probe that extends into the HVAC duct. Air flowing through the duct is forced into the vent holes on one side of the probe, into the enclosure, over the CO₂ sensor, and then the air is drawn back out of the enclosure via the vent holes on the opposite side of the probe. Optional temperature sensor and adjustable relay output is also available.

GS-AQDPM Series

The GS-AQDPM Duct Particulate Matter Sensor uses an optical sensor based on laser scattering principles and features innovative contamination resistance technology to perform highly accurate and reliable PM measurements.

The replaceable sensor measures particles of PM1.0, PM2.5, PM4.0, or PM10, with a continuous operation lifetime of more than 8 years. The sensor will provide long-term reliability and high resolution particle size binning for the detection of environmental dust and other particles.

Outside Particulate Matter Sensor

GS-AQOPM Series

The GS-AQOPM Outside Particulate Matter Sensor uses an optical sensor based on laser scattering principles and features innovative contamination resistance technology to perform highly accurate and reliable PM measurements. The replaceable sensor measures particles of PM1.0, PM2.5, PM4.0, or PM10, with a continuous operation lifetime of more than 8 years. The sensor will provide longterm reliability and high resolution particle size binning for the detection of environmental dust and other particles.

Room Air Quality Sensors

GS-AQR Series

The GS-AQR, Indoor Air Quality Sensor Series uses an advanced MEMS metal oxide semiconductor sensor to detect poor air quality. The sensor reacts quickly to detect a broad range of VOCs such as smoke, cooking odors, bio-effluence, outdoor pollutants and from human activities. The sensor captures all VOC emissions that are completely invisible to CO₂ Sensors. The GS-AQR Series provides a linear analog signal output of 0-5 or 0-10 Vdc for connection to a building automation system as well as an analog stepped output of 0-10Vdc. Optional features such as a temperature sensor, manual override and adjustable relay output are available.

Room Carbon Dioxide Transmitter
