Gas detector DEX-3K/N-HT-Nstd for organic compounds, custom calibration, F4-HT-B design (high-temperature version up to +80°C), catalytic sensor, brass housing

Gas detectors – reliable safety in any environment

The DEX-3K/N-HT gas detector is an advanced device designed for continuous monitoring of organic compound concentrations in the air. Equipped with a catalytic sensor, this detector provides fast and precise detection, which is crucial for ensuring safety in potentially hazardous environments. This model features custom calibration, adjusting sensitivity to specific user needs. The F4-HT-B version, i.e., the high-temperature version, allows operation in harsh conditions, even up to +80°C. The brass housing guarantees durability and corrosion resistance, making it an ideal solution for both industrial and commercial applications.

Construction and application

The DEX-3K/N-HT detector is designed to work with various Gazex control modules (MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16 and MDD-1, MDD-1/T, MDD-1x/T), allowing integration with existing alarm and control systems. The device finds application wherever there is a risk of organic gas leaks – from laboratories and industrial plants to underground car parks and sewage treatment plants. The high-temperature version expands the range of applications to areas exposed to elevated temperatures.

Key features and benefits

• High sensitivity and precision: The catalytic sensor ensures reliable detection of organic compounds even at low concentrations.
• Custom calibration: The ability to adjust the measurement range to individual user needs increases monitoring efficiency.
• Durable construction: The brass housing protects the device from mechanical damage and corrosion.
• Operation at high temperatures: The F4-HT-B version allows operation at temperatures up to +80°C without loss of measurement accuracy.
• Compatibility with Gazex systems: Easy integration with Gazex control modules provides a comprehensive solution for gas detection.
• ATEX compliance: The detector meets the requirements of the ATEX Directive, guaranteeing safe use in potentially explosive areas (detailed information available in the technical documentation).
• Replaceable sensor modules: Allow for quick replacement of a damaged sensor and adaptation of the detector to detect other gases (depending on module availability).
• Calibration in an accredited laboratory: Detectors are calibrated in their own GAZEX Calibrating Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which ensures the reliability of measurements.

The DEX-3K/N-HT detector is an investment in safety and peace of mind – both for installers responsible for the correct installation and configuration of the gas detection system, and for end-users benefiting from the monitored facility. Thanks to precise measurements and a reliable construction, it minimizes the risk of dangerous situations related to the presence of organic gases in the air.
