Innovative Solutions for Livestock Monitoring

AxetrisResearchers at Harper Adams University, Shropshire, United Kingdom, built and tested a multi-channel ammonia monitoring system by integrating the Axetris LGD F200 with the goal of developing a system which would provide substantially higher measurement performance, while being cost-efficient and robust for real-world use. Extensive tests were conducted over the span of multiple years, and the LGD F200 was shown to fulfi ll all major requirements.

"The Axetris LGD F200 offered an excellent alternative to existing ammonia monitoring solutions. Over the three-phase project that we undertook, we found the LGD F200 to provide extremely reliable and repeatable values. The product is suitable to build a cost-effi cient and robust ammonia measurement system for livestock applications" - Dr. Tomas Norton - Project Lead, Harper Adams University.

Ammonia monitoring solutions are needed to design effective scrubbing and ventilation systems, but must also be cost-effective in order to provide real-world feasibility for the livestock industry. The monitoring solution should be extremely robust, and designed for use in a diffi cult measurement environment, with no cross-sensitivity to a number of gaseous components, while also displaying high repeatability, even during continuous use. Existing solutions are mostly based on electrochemical sensing technologies, which are extremely prone to sensor poisoning, which can lead to false results, and suffer from a short lifetime.

Axetris LGD F200 OEM Modules are used in a variety of environmental and process applications for gas analysis.

The Axetris LGD F200 uses Tunable Diode Laser Spectroscopy (TDLS or TDLAS) for ammonia measurement, and provides an excellent fi t for livestock applications: Low ppm limit of detection (LoD), excellent accuracy and repeatability, high robustness for real-world continuous use, easy integration by OEMs according to customer requirements, outstanding cost-effectiveness and compact size.

The Laser Gas Detection (LGD) products from Axetris are available for gases such as ammonia (NH3), methane (CH4), hydrochloric acid (HCl) and carbon dioxide (CO2), in both ambient and heated (190°C) versions.
