ES101NH3 - 50ppm | 100ppm | 500ppm
  1.  Outdoor Ammonia NH3 Sensor

ES101-NH3 is an intergraded out-door sensor box for Ammonia NH3 monitoring. The monitoring data could be access through RS-485 interface by Modbus protocol. The ammonia sensor is designed with rapid response time and can withstand heavy interference. By the compensation algorithm and multi-stage standard gas calibration, it can achieve high precision, high repeatability and high stability. The IP65 outdoor enclosure is suitable for agricultural greenhouses, farms, pesticide manufacturers, chemical plants and other applications that require real-time monitoring and control of ammonia.
