BTMETER BT-535G Ammonia Detector NH3 Concentration Detector Measuring Range 0-100ppm Resolution 0.1 PPM, Alarm, Temperature (℉/°C), Humidity, Poultry Farm, Research with LCD Backlight Display

Brand: BTMETER
  • High Precision Analysis: Unlike traditional ammonia (NH3) detectors, BTMETER air quality detector 535G quickly detects ammonia concentrations of 0-100ppm in 120 seconds, making it extremely sensitive to changes in NH3 gas concentration, allowing you to accurately measure the level of concentration within ±5% of error. Detection resolution is 0.1ppm, ensuring accurate measurement accuracy
  • LCD Display with Backlight: Equipped with a backlit LCD display that clearly displays ammonia data even in dim environments. There is a hanging hole on the back of the monitor and a 180° rotatable stand that can be placed on a table or hung on a hand to check air quality. You can also use the wall for continuous monitoring
  • 【Adjustable Alarm Settings】The BTMETER NH3 gas detector has an ammonia alarm system that allows you to customize two ammonia alarm levels for added safety. When the detected ammonia concentration reaches the preset safety limit, the detector will immediately activate the buzzer and LED indicators and alert the user in a double way
  • Humidity and Thermometer: When monitoring ammonia concentration, you must pay close attention to the changes in ambient temperature and humidity. Measurement is done with an indoor temperature range of -14 - 122 °F (-10 - 50 °C), accuracy +/- 6.6 °F (2 °C), and relative humidity of 0 - 95 %. It can also be freely switched between temperature units of Celsius and Fahrenheit to meet the needs of different users
  • Long Lasting Sensor: BTMETER Air Quality Tester has a built-in 2,000 mAh lithium-ion battery that can be standby for about 4 hours after a full charge. USB Type-C charging cable included for easy charging
