Lumense Ammonia Monitor

The Lumense Ammonia Monitor is designed for use in concentrated animal feed operations and is especially useful in broiler grow-out houses. Continuous optimization of ammonia levels in these houses can increase processing yield and feed efficiency, reduce bird stress and disease, and improve bird uniformity. Experts estimate that control of ammonia at levels below 25 parts per million can improve bird performance by five to seven percent. At ammonia levels above 50 ppm, the spread of disease can accelerate to the point where a whole flock can be quickly lost. Mortality generally goes up as ammonia increases, and valuable parts of the bird, like the breast and feet, are damaged by high levels of ammonia. Even fifteen minutes of exposure to high ammonia levels can permanently stunt growth, especially for young chicks.

Ammonia is typically “monitored” by taking occasional measurements using disposable tubes or other portable instruments, by trying to “smell” ammonia levels, and/or by tracking in-house humidity. Ventilation regimens set using these approaches often become ineffective, particularly at nighttime. Many growers think that, by applying litter treatment, they have complete control of ammonia. The truth is that the performance of litter treatment can vary widely depending on house conditions, which can quickly change or be difficult to determine. Humidity levels are, at best, only a loose proxy for ammonia, and are often completely unrelated.

Features of Lumense’s Ammonia Monitor include:

  • Accurate ammonia detection from 5-300 ppm
  • Automated, durable and low maintenance sensor
  • Low-cost, both upon installation and in service
  • Predicted to pay for itself in just a few flocks.
  • Replaces manual spot checks and disposables
  • USB and standard analog controller interfaces
  • Real-time response for continuous monitoring
  • High specificity to ammonia
  • User-settable warning and danger thresholds

The Lumense Ammonia Monitor would be mounted on the interior wall in the control room of the poultry house, near the house controller. The sensor would continuously draw air from the poultry house, and exhaust it back into the house. A Feather and Dust Filter on the sensor intake, positioned close to bird breathing level, would prevent debris from entering the sensor. Inside the control room, the sensor could be used to regularly provide ammonia readings to the house controller, and would be connected to 110 or 220 VAC power.
