Portable NH3 Ammonia Gas Detector IECEx ATEX Certified IP68 Waterproof Single Gas Detector

Safegas MiniMeta single gas monitor customized for ammonia (NH3), equipped with high-precision electrochemical sensor, optional measuring ranges of 0-100ppm and 0-200ppm with 0.1ppm resolution. IP68 waterproof & dustproof, Ex ia IIC T4 Ga explosion-proof certified. It supports 2 years standby time with replaceable 3.6V dry battery, triple alarm and power-on self-test, optional docking station for bump test and data logging, widely used in refrigeration, fertilizer, livestock and chemical industries.

MiniMeta is IECEx, ATEX and EMC certified single gas detector under Safegas brand, specially designed for continuous ammonia monitoring. Adopts stable electrochemical sensing technology with two standard measuring ranges to match different industrial safety standards. The device features ultra-low power design, eliminating frequent charging and regular calibration within 2-year service cycle. Fully sealed IP68 housing adapts to humid, corrosive and dusty working environments. Built-in multi-level alarm reminder system and automatic self-check function guarantee stable long-term operation. Optional single or multi-unit docking station supports centralized calibration, bump test and data export to simplify daily equipment management. Only 125g lightweight body with back clip allows all-shift wearable personal gas protection.

• IP68 fully sealed casing, stable operation within -20℃~55℃ and 0-95%RH non-condensing atmosphere, resistant to ammonia mist, industrial dust and water splashes
• Replaceable non-rechargeable 3.6V dry battery delivering up to 2 years standby time, greatly reducing routine maintenance workload and overall operation cost
• Integrated triple alarm system consisting of 95dB buzzer, dual bright red LED and vibration, freely adjustable high/low alarm thresholds with automatic TWA, STEL and low battery prompts
• Automatic power-on self-test mechanism, LCD synchronously displays gas type, real-time concentration, MAX, MIN, TWA, STEL and residual battery capacity for full data reference
• Modular sensor and battery for independent replacement; optional event data logging and matched docking station for unified calibration and record export
• Mini-sized with 125g net weight, equipped with back clip for lightweight long-time wearing

Ammonia is a colorless, highly irritating toxic gas with corrosive properties, widely applied in multiple industrial and agricultural sectors. Short-term inhalation of high-concentration ammonia will severely irritate human eyes, respiratory tract and mucous membranes; long-term exposure may trigger pulmonary edema and permanent organ damage.

Besides toxicity, ammonia forms flammable mixtures with air within 16%-25% volume fraction, bringing fire and explosion risks once contacting open flame. In agricultural farms, ammonia accumulates from livestock manure decomposition, threatening both animal growth and staff health. In cold storage and chemical workshops, liquid ammonia leakage easily produces high-concentration gas clouds. Real-time portable monitoring can timely detect abnormal concentration changes, avoid poisoning accidents, and help factories comply with occupational health and environmental emission standards.

Cold Storage & Refrigeration Workshop

Large industrial refrigeration systems adopt liquid ammonia as refrigerant; the detector monitors pipeline and equipment leakage to prevent toxic gas overflow.

Fertilizer Manufacturing Plant

Ammonia is core raw material for nitrogen fertilizer production; wearable detectors offer continuous personal protection for frontline production operators.

Livestock & Poultry Breeding Farm

Decomposed livestock waste generates ammonia; real-time monitoring controls indoor concentration to protect breeders and animal health.

Semiconductor & Electronic Workshop

Dilute ammonia solution is used for chip cleaning; trace leakage monitoring avoids equipment corrosion and staff inhalation hazards.

Pharmaceutical & Chemical Synthesis Factory

Ammonia participates in fine chemical synthesis; portable instruments detect gas overflow in reaction workshops.

Confined Space & Wastewater Treatment Tank

Sewage decomposition generates ammonia; pre-entry gas inspection eliminates hidden safety risks in closed spaces.
