Advanced Electrochemical Gas Sensors for Precise Air Quality Monitoring
Reliable, cost-effective electrochemical sensing systems for emissions control, gas detection, and industrial safety compliance
Overview
Electrochemical gas sensors are critical tools in modern industrial gas detection and emissions monitoring. These compact sensors detect toxic and combustible gases through a chemical reaction that generates an electrical signal proportional to the gas concentration. Known for their sensitivity, low power consumption, and selectivity, electrochemical sensors are ideal for applications where accuracy and safety are paramount.
They are extensively used in stack monitoring, confined space entry, ambient air quality monitoring, and safety systems across industries like oil & gas, waste management, and utilities. With multi-gas detection capability and a wide selection of target gases including CO, NO₂, H₂S, and SO₂, they help ensure workplace safety and environmental compliance. Emissions and Stack supports North American B2B clients by delivering reliable, cost-effective electrochemical gas sensing systems tailored to industry-specific requirements, backed by expert technical support and smart integration tools.
