SO2 Analysers
Sulphur dioxide is formed whenever sulphur containing fuels or materials are burned or processed, and it is one of the most closely regulated industrial emissions. It also plays a part in acid gas treatment, sulphuric acid production, and refinery operations, where its concentration tells operators how well a process is performing. Accurate SO2 measurement supports emissions compliance, protects equipment from acid corrosion, and helps control desulphurisation processes. SO2 is soluble and corrosive, so the sample must be handled carefully from the stack to the analyser, which makes the sampling system as important as the analyser itself. TC Limited manufactures SO2 analysers for emissions monitoring and process control, and every analyser is supplied complete with a sampling system matched to your application.
TC-S2 100 Infrared SO2 Analyser
A dependable analyser using infrared absorption for continuous SO2 measurement in process and flue gas. Stable readings and low drift suit plants that need straightforward monitoring with little maintenance. Supplied complete with a sampling system including filtration, gas cooling, and flow monitoring.
TC-S2 200 Ultraviolet SO2 Analyser
Uses ultraviolet absorption for selective, fast SO2 measurement, including low concentrations and wet gas streams where water vapour can interfere with other methods. Well suited to emissions monitoring and desulphurisation control. Supplied complete with a sampling system with heated components to prevent condensation and sample loss.
TC-S2 300 Flue Gas Desulphurisation Analyser
Built for power stations and industrial plants with scrubbers, measuring SO2 at the inlet and outlet to confirm removal efficiency. It copes with hot, wet, dusty, and corrosive gas. Supplied complete with a sampling system including a heated probe, heated filter, and corrosion resistant sample line.
TC-S2 400 Multi Component Emissions Analyser
A rack mounted analyser that measures SO2 together with gases such as NO, NO2, CO, CO2, and O2, with automatic calibration checks and alarm outputs. One unit covers the full set of components in a continuous emissions monitoring system. Supplied complete with a sampling system including sample conditioning, flow control, and calibration gas connections.
