Leading the market with the most advanced and accurate outdoor monitoring system
The WT1 Pro is expertly designed for outdoor environments, particularly industrial sites, that require advanced emission monitoring both at the fencelines and at the source, whether surface-based or channeled. It delivers precise quantification and identification of emissions, with odor analyses aligned with reference standards (EN 13725, ASTM 679). Featuring customizable capabilities, the WT1 Pro captures real-time data on physical, chemical, and perceptual parameters (gases, odors, particles, etc.).
The WT1 Pro offers continuous and simultaneous monitoring of a broad range of sensory parameters, tailored to meet the specific needs of your operations. Whether you oversee a wastewater treatment plant, a waste recovery facility, an airport, a port, a heavy or processing industry, or a construction site, the WT1 Pro is designed to meet your exact requirements.
When integrated with the EllonaSoft platform, the WT1 Pro provides real-time alerts that facilitate proactive and informed decision-making to enhance environmental management. It also supports the initiation of remediation actions, either via its API or through wired connections, ensuring a swift and effective response to emission challenges while strengthening risk management and operational compliance.

Alerts & notifications
The Ellona platform enables you to set up a range of real-time alerts and automate the creation of insightful reports.
Automated remediation activation
This feature, integrated particularly with the WT1 Pro, allows for the automation of triggering third-party systems (such as sampling, misting, ventilation, etc.) through precise management of ON/OFF devices and 4-20 mA inputs, or via the API. This automation ensures a rapid and appropriate response in the event of a detected incident.
Feedback on human perception
Ellona’s solutions feature real-time feedback functionality, allowing individuals to report their environmental perceptions and refine the analysis algorithms accordingly.
