Gas detector DEX-4K/N-HT-Nstd ammonia, custom calibration, F4-HT-C design (high-temperature version up to +80°C), catalytic sensor, brass housing

Gas detectors – reliable protection and precise measurement

The DEX-4K/N-HT gas detector is an advanced device designed for continuous monitoring of ammonia concentration in enclosed and open spaces. Equipped with a catalytic sensor, the detector provides a quick and reliable response to hazards, making it an ideal solution for both industry and public facilities. This model stands out with the possibility of custom calibration, adjusting sensitivity to specific user needs. The F4-HT-C version, with a brass housing and high-temperature resistance up to +80°C, guarantees durability and reliability even in harsh environmental conditions.

The detectors of the DEX/F series are an integral part of gas hazard signaling systems, cooperating 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). They meet the requirements of the ATEX Directive, confirming their safety of use in potentially explosive atmospheres. Replaceable sensor modules with built-in compensation algorithms ensure precise measurements and minimize the risk of false alarms.

• Wide application: ideal for monitoring ammonia in the chemical industry, agriculture (cold stores), wastewater treatment plants and other facilities where there is a risk of gas leakage.
• Durable construction: brass housing provides resistance to corrosion and mechanical damage.
• High operating temperature: high-temperature version (+80°C) allows mounting in places exposed to elevated temperatures.
• Custom calibration: possibility to adjust the measurement range to individual user needs (standardly 5/15% LEL).
• Compliance with standards: meets the requirements of the ATEX Directive guaranteeing safety of use in explosion-prone zones.
• Easy integration: compatible with GAZEX control modules facilitates the construction of complex gas detection systems.
• Replaceable sensor: the ability to quickly replace a damaged sensor minimizes system downtime.

The DEX-4K/N-HT detector is not only an effective tool for protecting against gaseous hazards, but also an investment in safety and work comfort. Thanks to precise measurements and a reliable construction, it provides peace of mind to both installers responsible for the installation and service of gas detection systems, and end-users benefiting from the monitored facilities. Regular calibration (recommended by the manufacturer) allows maintaining high measurement accuracy for a long time of device operation.
