Gas detector DG-71/N – reliable acetylene and hydrogen detection

This gas detector is designed to work with MD and MDP series control modules, providing effective protection against the risk of explosion or poisoning by acetylene (C₂H₂) and hydrogen (H₂). The device is characterized by high measurement accuracy thanks to the use of a semiconductor gas sensor. It is an ideal solution for both installers of gas detection systems and end-users looking for reliable protection.

Construction and application

The DG-71/N detector is a threshold device, signaling the exceeding of defined gas concentration values. It finds application in places where there is a risk of acetylene or hydrogen leakage – in workshops, laboratories, production plants, as well as in warehouses and technical rooms. Its compact dimensions (110 x 140 x 55 mm) facilitate installation in various locations. The built-in optical signaling (LED lamp) informs about the detector's operating status and exceeding alarm thresholds.

Key features and benefits

• Replaceable sensor: Enables quick and economical replacement of a damaged sensor or adaptation to other measurement needs.
• Two alarm thresholds: Allow precise setting of alarm values, adapted to the specifics of the working environment.
• Built-in event history: Facilitates analysis of the causes of alarms and optimization of the gas detection system (analysis available from the manufacturer).
• Thermal compensation circuit: Ensures stable readings even under changing environmental conditions.
• Splash-proof housing (IP44): Protects the device from moisture and ensures reliable operation in difficult conditions.
• Easy installation and operation: Thanks to the modular design and simple connections, the installation and configuration of the detector are quick and intuitive.
• Calibration in an accredited laboratory: Guarantee of measurement accuracy confirmed by PCA accreditation No. AP150 in accordance with PN-EN ISO/IEC 17025 standard.
• Standard alarm thresholds: 10/30% LEL (Lower Explosive Limit), allowing for quick device start-up without time-consuming calibration.

The DG-71/N detector is a conventional design and cannot be used in areas at risk of explosion of gases, vapors or dust. Please keep this in mind when choosing the installation location. The interchangeability of modules with a semiconductor and electrochemical sensor enables flexible adaptation to specific application needs.
