Gas detector DG-7E/N hydrogen, 500/800ppm, electrochemical sensor

Gas detector DG-7E/N – reliable hydrogen detection

The DG-7E/N gas detector is a device designed for continuous monitoring of hydrogen concentration in industrial and enclosed spaces. Equipped with an electrochemical sensor, it provides a precise measurement in the range of 500-800 ppm, making it an ideal solution for applications requiring high sensitivity and accuracy. The detector signals exceeding permissible gas concentration levels using a built-in optical alarm.

Application and functionality

The DG-7E/N detector finds application wherever there is a risk of hydrogen leakage, e.g. in laboratories, production plants using hydrogen as a raw material or fuel, hydrogen refueling stations and gas storage facilities. The device is designed to cooperate with MD and MDP series control modules, enabling integration with alarm and control systems. It is important to remember that the detector has a standard construction and cannot be used in potentially explosive areas.

Key features and benefits

• Replaceable sensor: Enables quick and economical replacement of a damaged sensor or adaptation of the detector to other gases. This significantly reduces operating and servicing costs.
• Two-level alarm signaling: Provides effective warning of exceeding permissible hydrogen concentrations. Alarm thresholds are set by the manufacturer, simplifying installation and configuration.
• High sensor selectivity: The electrochemical sensor is characterized by high selectivity to hydrogen, minimizing the risk of false alarms caused by the presence of other gases.
• Durable construction: The housing made of high-impact ABS provides resistance to mechanical damage and environmental conditions (IP44).
• Calibration: Each detector is factory calibrated in its own GAZEX Calibration Laboratory (PCA accreditation No. AP150), which guarantees measurement accuracy and compliance with standards.
• Simple installation: Modular design and no need for on-site calibration facilitate and speed up detector installation.
• Compact dimensions: Dimensions of 110 x 140 x 55 mm allow for easy integration of the detector into existing infrastructure.

The DG-7E/N detector is a reliable tool for monitoring hydrogen concentration, which ensures work safety and protects against potential hazards related to gas leakage. Its solid construction, high measurement accuracy and ease of use make it an ideal choice for both professional installers and end users.
