OC-905 portable pump-suction ammonia gas detector is a handheld gas monitor with built-in sampling pump. It adopts high-precision NH3 sensor to quickly and accurately detect ammonia concentration on site. LCD screen displays real-time gas data, and sound-light alarm will trigger when concentration exceeds preset threshold. Compact handheld design supports mobile field inspection for ammonia leakage safety monitoring.
Product Overview
This portable NH3 Ammonia Gas Detector is designed to monitor ammonia (NH₃) concentration in ambient air in real time. Equipped with high-precision electrochemical sensor, the device supports continuous detection of ammonia leakage. With audible, visual and vibration triple alarms, it effectively reminds operators of excessive NH3 concentration. Widely applicable to poultry farms, livestock breeding plants, chemical workshops, refrigeration stations, wastewater treatment plants and other scenarios where ammonia may accumulate.
