AQBot SO2 Air Quality Monitor

AQBot SO₂ is a sulfur dioxide monitoring system designed for continuous measurement of SO₂ concentrations in demanding industrial environments. Equipped with a high-performance electrochemical sensor, this SO₂ monitor delivers accurate, real-time measurements to support workplace safety, emission monitoring, environmental compliance, and process control across refineries, petrochemical plants, chemical industries, pulp and paper mills, wastewater treatment facilities, and other SO₂-sensitive applications.

The system continuously measures sulfur dioxide concentrations and provides instant on-site visibility through its integrated display. The alarm siren and strobe light enable rapid response when user-defined thresholds are exceeded, helping organizations detect hazardous SO₂ levels before they become safety risks.

Built for long-term outdoor deployment, the SO₂ monitor features an IP66-rated sensing module housed within a rugged NEMA 4X enclosure for reliable performance in harsh industrial conditions. It supports flexible wall or pole mounting, on-site or laboratory calibration, and multiple communication interfaces for seamless integration with existing monitoring and plant control systems. Integrated with Envizom, it provides live dashboards, smart alerts, automated reports, historical analytics, REST APIs, and relay-based automation for real-time environmental monitoring and operational control.
