Manufacturer doesn't allow for price to be posted. Please request a quote:

The SPH Engineering FluX Ammonia Core Sensor is a UAV-integrated gas sensor measuring ammonia (NH3) with simultaneous water vapor (H2O) measurement for humidity correction. Delivering accurate, humidity-corrected ammonia concentration data in-situ from a drone platform, it is designed for agricultural emissions mapping, industrial ammonia leak detection, and environmental air quality monitoring — where water vapor interference makes uncorrected NH3 measurements unreliable. Integrated with SkyHub and UgCS for georeferenced, real-time ammonia data acquisition.

NH3 Detection. H2O Corrected. Accurate in Any Humidity.
The FluX Ammonia Core Sensor measures ammonia (NH3) and water vapor (H2O) simultaneously — using the H2O measurement to correct NH3 readings for humidity-induced interference in real time. Water vapor is a primary source of measurement error in uncorrected ammonia sensors, particularly in agricultural environments where humidity levels vary significantly across survey areas and seasons. By correcting for H2O at the point of measurement, the FluX NH3/H2O sensor delivers accurate ammonia concentrations across the full range of atmospheric conditions encountered in field operations. Integrated with SkyHub for georeferenced acquisition and UgCS for real-time ground station monitoring.

H2O Correction. Accurate NH3 in Any Humidity. Water vapor is a primary interference source for ammonia sensors — causing measurement errors that increase with humidity. The FluX NH3/H2O sensor eliminates this error by measuring H2O simultaneously and correcting NH3 readings at the point of acquisition, delivering reliable ammonia concentrations regardless of atmospheric humidity conditions.

Agricultural Emissions Mapping. From the Air. The FluX Ammonia sensor enables rapid, large-area aerial mapping of ammonia emissions from livestock facilities, manure management operations, and fertilizer application areas — providing the spatial resolution and coverage efficiency that ground-based monitoring networks cannot achieve.

Georeferenced NH3 Maps. Regulatory-Ready from Landing. Ammonia concentration data is captured with synchronized GPS position throughout the mission via SkyHub — producing georeferenced NH3 maps that integrate directly into GIS platforms and reporting workflows for environmental compliance, regulatory submissions, and agricultural emissions documentation.

The SPH Engineering FluX Ammonia Core Sensor is a UAV-integrated dual-measurement gas sensor detecting ammonia (NH3) with simultaneous water vapor (H2O) measurement for humidity correction. Designed for in-situ aerial ammonia surveys, it delivers accurate, humidity-corrected NH3 concentration data in agricultural, industrial, and environmental monitoring applications — where water vapor interference is a primary source of measurement error in uncorrected ammonia sensors.

Key Features

  • NH3 Detection with H2O Correction — Simultaneous ammonia and water vapor measurement; H2O data is used to correct NH3 readings for humidity-induced interference, delivering accurate ammonia concentrations across varying atmospheric conditions
  • In-Situ Contact Sensing — Measures ammonia concentration in the ambient air mass directly surrounding the drone — ideal for close-proximity emissions mapping, low-altitude agricultural surveys, and industrial facility inspection
  • SkyHub Integration — Integrates with the SkyHub onboard computer for automated, georeferenced NH3/H2O data acquisition synchronized with UAV GPS position and telemetry
  • Real-Time UgCS Monitoring — Live ammonia concentration data streamed to the UgCS companion application on the ground station for immediate anomaly detection and operator awareness during flight
  • Georeferenced Data Output — NH3 concentration data logged with synchronized GPS position for direct GIS integration and regulatory reporting

Applications

  • Agricultural ammonia emissions mapping (livestock facilities, manure management, fertilizer application)
  • Environmental compliance and air quality monitoring near agricultural operations
  • Industrial facility ammonia leak detection (refrigeration systems, chemical plants)
  • Wastewater treatment plant emissions monitoring
  • Regulatory reporting and environmental impact assessment

Requirements

  • SPH Engineering SkyHub onboard computer (required)
  • SkyHub Core Software Package and compatible SkyHub gas sensor software package (required)
  • UgCS ground control software (required)
