NH3100 Ammonia Sensor Agriculture Quality | Monitrol

Our ammonia sensor measures NH3 gas up to 100 ppm (parts per million) in the air, converts the measurement to a 420 mA signal and transmits the information to your controller. This important data will help you adjust your ventilation and heating quickly and bring your NH3 level below 25 ppm (Maximum concentration according to the Government of Ontario).
