Gas detector DEX-P4K/N-HT-Nstd ammonia, measurement range on request, P4-HT-C design (high-temperature version up to +80°C), catalytic sensor, brass housing

Gas detectors – reliable protection for installations

The DEX-P4K/N-HT gas detector is an advanced device designed for continuous monitoring of ammonia concentration in enclosed spaces. The P4-HT-C design, with a brass housing and steel sinter, ensures durability and corrosion resistance, and the high-temperature version allows operation in harsh conditions, up to +80°C. The device uses a catalytic sensor, which is characterized by high measurement accuracy and stable operation.

This detector is a key element of safety systems in many industrial and commercial applications. Its task is to detect dangerous concentrations of ammonia, which allows for a quick response and prevention of potential threats to health and life. Thanks to the possibility of configuring the measurement range (standard 20% LEL or other on request), the detector can be adapted to the specific needs of a given application.

Construction and functionality

The DEX-P4K/N-HT detector is designed for reliability and easy integration with existing alarm systems. It has an analog current output of 4-20mA, which allows cooperation with various measuring modules and control centers. The device meets the requirements of the ATEX Directive, which guarantees its safe use in potentially explosive atmospheres. The explosion-proof flameproof enclosure allows installation in zones threatened by the explosion of gases or flammable vapors (IIA, IIB, IIC) of various temperature classes (T1-T6).

It is worth emphasizing that GAZEX detectors are calibrated in their own Accredited Calibration Laboratory in accordance with the PN-EN ISO/IEC 17025 standard. This ensures high measurement accuracy and reliability of results. The sensor module can be easily replaced, which reduces operating costs and extends the life of the device. Additionally, the detector has built-in thermal and linear compensation algorithms, which minimize the impact of environmental conditions on measurement accuracy.
