High Sensitivity NH3 Detection: The ammonia gas detector accurately measures NH3 levels from 0-200 PPM with a resolution of 0.1 PPM, accuracy +/-5%. This NH3 gas detector is perfect for detecting ammonia gas leaks in various environments Visual & Audible Alarm: This NH3 ammonia detector allows you set high/low ammonia limits. when the NH3 level exceed the value, the ammonia detector beep, vibration and the indication flash light. The sound and vibration frequency increase when the AUL is reached Wide Application: Equipped with a high-quality electrochemical ammonia sensor for accurate detection of ammonia gas leaks. This NH3 detector ideal for use in poultry, pig farms, livestock monitoring, ambient air ammonia testing, and industrial ammonia monitoring Rechargeable NH3 Meter: Digital NH3 monitor built-in rechargeable battery, included Type-C cable can be connected to the plug for charging. It operates for about 16 hours on a full charge. Auto/manual power-off feature to save battery life Ammonia & Temp & Humidity Meter: Ammonia gas concentration, ambient temperature(℃/℉), and humidity are displayed on the 2.8inch LCD color screen. With adjustable brightness, the NH3 air quality monitor ensures clear indoor and outdoor readings Please note: the physical slightly color difference or difference, does not affect the use, please do not mind, thank you! Easy to Use: Simply press the power button for 3s to turn on the ammonia gas monitor. The ammonia air detector displays the maximum NH3 value and records up to 1,000 data groups. Includes a stand and clip and measure ammonia (NH3) gas density continuously Voltage: AC110V Plug Type:US Plug,it applies to Canada, India,Mexico, Thailand, the United States, the Philippines,Taiwan and so on.
