High Precision Electrochemical NH3 Ammonia Detector, Triple Sound Light Vibration Alarm, Ideal for Livestock Farm, Ammonia Refrigeration, Chemical Factory
Prevent NH3 Poisoning & Gas Risks, Professional Ammonia Gas Detector for On-site Safety Inspection
Control NH3 concentration, Standardize industrial gas safety management.
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.
Features:
Used original imported sensors and ultra-low power 32 bit microprocessor
The circuit adopts 4-layer wiring, which is stronger for weak signal processing and anti-interference ability
Intelligent algorithm + multi-point calibration + temperature compensation, more accurate measurement results
2.5 inch dot matrix display interface,reading intuitively
All English operation menu and easy operation.

Function:
Inspect the gas concentration and alarm when it reaches preset alarm level.
High accuracy, good stability and good repeatability, long working life.
One-key operation to restore to factory default setting.
Adjustable two-stage audible-visual alarm threshold value.
Powered by rechargeable lithium battery with big capacity.
The built-in pump, stable flow rate, can be opened or closed.
