Our health depends on the quality of air we breathe!


The Watchtower 1 (WT1), when tailored to your industrial sector, not only monitors for olfactory and chemical output, it also allows improved communication with local residents and authorities. Local residents can be empowered to work with you, providing direct feedback along with the data collected by the WT1. This ability provides you with a better understanding of any odour problem, enabling you to adjust on-site operations to reduce any nuisances.


These adjustments not only provide better, healthier air quality, they also provide an optimised operation for odour control around your facilities, leading to drastic cost reductions.

The Watchtower 1 is one of the most reliable tools for decision making within a continuous improvement approach (ISO 14001, ISO 9001).

How it works:

  • Fence-line monitoring with direct reading of H2S and NH3 concentration plus 2 further optional gas concentrations.

  • Direct reading of each MOS sensor’s output, as well as in combination, for source identification on-line with propriatory data processing.

  • Communication via LoRa (up to 1 km) or GPRS.

  • Autonomous with recheargeable battery and solar panel (requires a minimum of 5 hours sun per day).

  • System can be ground wired for those less fortunate!

  • 1 Hour installation, 2 days of battery, plus 2 days of data storage in case of loss of communication.

  • Source identification with pattern recognition built-in software and automatic sampling (optional).

  • Automatic plug-in installation and self configuration (central controller for easy reconfiguration and adaptation).

  • Autocalibration and easy maintenance.

  • Olfactory and chemical monitoring tailored to your industrial sector.

  • Improved communication with residents and authorities.

  • Better understanding of the odour problem enabling adjustment of on-site operations.

  • Optimised operation of odour control facilities leading to drastic cost reduction.

  • Efficiency of air treatment processes continuously monitored.

  • Reliable tool for decision making within a continuous improvement approach (ISO 14001, ISO 9001).
