    Introducing the cGas-SD: A Smart Solution for Hard-to-Reach Gas Monitoring Challenges

    The cGas-SD Sample Draw System elevates your safety standards with precision monitoring.

    The cGas-SD is a self-contained, single sensor, sample draw monitoring system designed to draw samples of air or gas from hard-to-access locations such as shafts, tall ceilings, wells, pits, small rooms and many other challenging environments.

    This innovative system ensures accurate monitoring of toxic gases or oxygen levels, providing reliable safety and compliance in various applications. It uses sample tubing to draw air from the monitored space, ensuring safety without compromising sensitive equipment. Its built-in sample draw pump, sensor, and flow detector work together to deliver accurate and consistent readings. The system also features smart alert capabilities, including both visual and audible alarms, as well as a blocked flow alert to notify users of unsafe conditions or system malfunctions.

    Designed with ease of use in mind, it includes an LCD display with LED indicators and external push buttons for straightforward configuration and calibration. Additionally, the CGAS-SD offers flexible output options, including configurable 4—20 mA or 0—10 V analog signals, BACnet® MS/TP or Modbus® RTU communication protocols, and a 5A relay for integration with external devices. It comes configured for line voltage power supply but is easily switchable to low voltage in the field.
