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

Gas Detectors – Reliable Safety in Your Installation

The DG-7E/N/W gas detector is an advanced device designed for continuous monitoring of hydrogen concentration in the air. It finds application in industrial and enclosed spaces where there is a risk of gas leakage. Its main task is to detect dangerous concentrations early on, allowing for a quick response and preventing potential hazards – from explosion to poisoning. The device is particularly useful in laboratories, production plants using hydrogen, as well as in warehouses and refueling stations.

Construction and principle of operation

The DG-7E/N/W detector is based on an electrochemical sensor, which is characterized by high sensitivity and selectivity in detecting hydrogen. It has two programmable alarm thresholds, allowing you to adjust the sensitivity to specific working conditions and safety requirements. If the set thresholds are exceeded, the detector signals an alarm visually using a built-in optical indicator. The modular design of the device facilitates sensor replacement in the event of calibration or damage, reducing operating costs and minimizing downtime. It is worth remembering that this detector is intended for use in places that do not require ATEX certification – i.e. where there is no risk of an explosive atmosphere.

Key features and benefits

• High measurement accuracy: The electrochemical sensor provides accurate and reliable measurements of hydrogen concentration in the range of 500/800 ppm.
• Two-stage alarm: Two programmable alarm thresholds allow for flexible adaptation of the device to specific needs and working conditions.
• Easy sensor replacement: The modular design facilitates and speeds up sensor replacement, reducing service and calibration costs.
• Optical signaling: The built-in optical signaling informs about the operating status of the device and exceeding the alarm thresholds.
• Reliability: The device is manufactured by the renowned company Gazex, which has an accredited calibration laboratory (PN-EN ISO/IEC 17025).
• Compact dimensions: Dimensions of 110 x 140 x 55 mm make it easy to mount in various locations.
• System power supply: Power supply from the system simplifies installation and eliminates the need for additional power sources.

Applications

The DG-7E/N/W detector finds wide application wherever there is a risk of hydrogen leakage:

• Chemical and research laboratories
• Production plants using hydrogen as a raw material or inert gas
• Hydrogen warehouses
• Hydrogen refueling stations
• Energy facilities using fuel cells
• Technical rooms with installations producing hydrogen

Let's remember the limitations – the device should not be used in areas at risk of gas or dust explosions.
