Gas detector DEX-41/N-Nstd ammonia, calibration on request >500ppm, F4-C design, p-p sensor, brass housing DEX-41/N-NSTD

Gas detectors for safety and comfort

The ammonia gas detector DEX-41/N-Nstd is a reliable device designed for continuous monitoring of ammonia concentration in the air. Made of high-quality materials, including a brass housing, it ensures durability and corrosion resistance, which is particularly important in harsh industrial conditions. This detector is a key element of safety systems in many applications, from production plants to refrigeration facilities and wastewater treatment plants.

Construction and operating principle

The DEX-41/N-Nstd detector uses a semiconductor sensor (p-p) for precise measurement of ammonia concentration. The explosion-proof flameproof enclosure allows for safe use in potentially explosive areas (IIA, IIB, IIC, temperature classes T1-T6). The device signals exceeding two alarm thresholds (A1, A2) set during calibration. Calibration on request, with a range above 500 ppm, ensures adaptation to specific user needs. F4-C execution indicates a specific detector configuration tailored to specific application requirements.

Applications and benefits

The DEX-41/N-Nstd detector finds application wherever there is a risk of ammonia leakage:

• Chemical industry: Monitoring production processes using ammonia.
• Agriculture: Controlling ammonia concentration in livestock buildings and fertilizer warehouses.
• Refrigeration: Detecting ammonia leaks from refrigeration systems.
• Wastewater treatment plants: Monitoring biological wastewater treatment processes.
• Food industry: Controlling ammonia concentration in food storage warehouses.

Using this detector translates to:

• Increased safety: Rapid detection of dangerous ammonia concentrations minimizes the risk of poisoning and accidents.
• Health protection: Continuous monitoring prevents long-term exposure to the harmful effects of ammonia.
• Compliance with regulations: Meeting the requirements of the ATEX Directive guarantees legality of use in potentially explosive areas.
• Reliable operation: High quality of workmanship and regular calibration ensure precise measurements for a long time.
• Ease of use: Modular design facilitates sensor replacement and device maintenance.

GAZEX detectors are calibrated in their own Calibrating Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation no. AP150), which confirms their high accuracy and reliability of measurements.
