Ammonia (NH₃) is a colorless gas with a sharp odor, widely used in refrigeration, fertilizer production, and chemical processing. While effective in cooling systems, ammonia leaks can be hazardous. Even small concentrations can irritate the eyes, nose, and throat, while higher levels may cause lung damage or pose life-threatening risks. That’s why having a reliable ammonia gas detector in sensitive areas is critical to workplace safety.
Ammonia gas is harmful. Short-term exposure to low levels can cause eye irritation, coughing, and throat burning. Prolonged or high-level exposure may lead to chemical burns, respiratory failure, or even fatal outcomes. Workers in industries like refrigeration, chemical plants, and cold storage must rely on ammonia gas sensors to detect leaks early and prevent accidents.
The test for ammonia gas is commonly called the Nessler’s Test, which detects ammonia in aqueous solutions by forming a yellow-brown complex. In industrial settings, however, advanced devices like the Evikon E2638-NH3-E Ammonia Detector provide continuous real-time monitoring—far more reliable and accurate than manual chemical tests.
In the UAE and GCC, extreme climate conditions demand robust refrigeration and cooling systems across industries, from hospitality and food storage to desalination and district cooling plants. Ammonia is widely used as a refrigerant, but leaks pose serious safety hazards. Regulatory authorities and civil defense departments increasingly mandate reliable ammonia gas detection systems to comply with safety codes. The Evikon E2638-NH3-E is designed to meet these stringent requirements, making it a trusted choice for engineering consultants, contractors, and facility managers.
