Gas detector DEX-12/N-HT-Nstd – reliable protection against methane

The DEX-12/N-HT-Nstd gas detector is an advanced device designed for continuous monitoring of methane concentration in the air. Equipped with a semiconductor sensor, the detector provides fast and precise detection of hazards, signaling the exceeding of two alarm thresholds. The high-temperature design (up to +80°C) and a robust aluminum housing make it an ideal solution for both demanding industrial applications and domestic gas installations. The device is designed to cooperate with GAZEX control modules, providing a comprehensive safety system.

Application and functionality

The DEX-12/N-HT-Nstd detector finds application wherever there is a risk of methane leakage, e.g. in gas boiler rooms, industrial plants, sewage treatment plants or production halls. Its main task is to protect life and property by early detection of dangerous gas concentrations. The possibility of custom calibration (10/30% LEL or other value) allows you to adjust the detector's sensitivity to specific working conditions. F4-HT-C execution guarantees reliable operation even at elevated temperatures.

Key features and benefits

• High sensitivity and precision: Semiconductor sensor provides fast and accurate methane detection.
• Durable construction: Aluminum housing protects the device from mechanical damage and external factors.
• Operation at high temperatures: High-temperature design (up to +80°C) allows mounting the detector in places with elevated ambient temperature.
• Calibration possibility: Adjusting the detector's sensitivity to individual user needs through custom calibration.
• ATEX compliance: Ensures safe use in potentially explosive atmospheres.
• Easy integration with alarm systems: Compatibility with GAZEX control modules facilitates the construction of a comprehensive safety system.
• Long service life and low operating costs: Replaceable sensor modules allow easy replacement of worn elements without the need to replace the entire detector.
• Calibration in GAZEX's own laboratory: Guarantee of measurement accuracy confirmed by PCA accreditation No. AP150 (PN-EN ISO/IEC 17025 standard).

Installation and operation

The installation of the detector should be carried out by a qualified installer in accordance with the manufacturer's operating instructions. Remember to place the detector in an appropriate place – on the wall, above the top edge of doors or windows, in an unshielded place and away from sources of interference (e.g. ventilation openings, heat sources). Regular checking of the technical condition and periodic calibration of the detector ensure its reliable operation for a long time. The detector is intended for operation only with MD type alarm modules manufactured by GAZEX.
