How does this work ?

Network of WT1 analyzers

  • Suitable for any type of emission source
  • Outdoor and indoor air analysis

Field weather stations(s)

Real-time measurments of local weather parameters influencing the dispersion of polluants. (RH, T°, wind speed, wind direction, rain, pyranometer )


A complete range of services

  • Odor audit
  • Odor diagnosis
  • Impact assessment
  • Zero state
  • Technical support
  • Training

Multiple monitoring levels

Modulable and scalable, the WT1 monitoring network is sized to your needs. Your results are available source by source, site by site or on a regional scale.

On-line results

With the RUBIX Soft SAS secured web site, use your web browser to access your data, 24/7, anywhere in the world.


Designed to monitor one or more sources or more industrial site(s), the WT 1 measurement network provides you with real-time key information for efficient management of chemicals and olfactory pollution.


Off line dispersion plume

  • Dynamic 3D mapping of dispersion plumes
  • Calculations of concentrations in the vicinity of the site(s)
  • Automated dispersion reports

Real-time alerts

  • Configurable alert threshold
  • Notification by warning siren, flashing light, SMS, email, etc.

On line alerts and source identification

  • Configurable alert threshold
  • Process control ( Bio filters, scrubbers, ventilation …)
  • Pattern matching software ( PCA, LDA, PLS )

Control of air treatment facilities

  •  Automatic activation & deactivation based on emissions levels
  • Amount of additives adjusted to the odor concentration

Cloud SaaS Based Hosting

The central monitoring station is hosted on a secure based server allowing remote access via any internet based computer. The access is restricted and the data is encrypted for maximum security. Users are given a password which will define their permission level. Operator access can simply view the results and create reports while administrator access can reconfigure the system and set all parameters.

Graphic Emission Representation and Reporting

The monitoring system continuously provides real-time readings of all sensors in the grid plus has the capability to show data for any defined instant in time. Furthermor reports such as specified period mean, high, low and variance for each sensor can be shown. Other reporting options such as sensor ranking in highest average reading and highest variation can also be requested.

Gases (ppm): Up to 8 different gases from a list of 15+ gases, depending on your business needs. Download the WT1 datasheet for reference
Particulate Matters (µg/m3): PM1, PM2.5 and PM10. Measuring those parameters in petrochemical sites, airports/seaports or even tunnels enables the monitoring and control of emissions and helps improve working conditions. For construction sites, a PM sensor for type fingerprinting is available on demand

Odors: Recognition of olfactive events for situational intelligence; increasing process and operational efficiency and controlling impact on close neighborhoods

VOC (µg/m3): Toxic chemicals are emitted by several activities and processes across sectors, impacting not only the environment but the health of workers and neighbors close by

Temperature (ªC): It makes all the difference when controlling industrial processes or ensuring employees’ comfort and well-being

Humidity (%): Too much or too little can have a big impact on the final output of your processes. Controlling it will optimize your business and maximize your profits

Atmospheric pressure (hPa): The right pressure will help you better controlling the concentration of certain gases

Noise (dBa): beyond managing the impact on close neighborhoods and employees’ working conditions, you can prevent and inform about risky or unexpected situations

Quality indices

Air Quality Index: advanced characterization of the level of overall pollution in the environment

Odor Index: number, intensity and persistence of olfactory events, providing an objective basis for olfactory nuisances felt on site
