Our Background
TC Limited’s story begins in the United Kingdom, where our engineers set out to solve a problem industry had struggled with for years: getting gas measurements that could be trusted in harsh process conditions. Our first precision gas analyser delivered dependable readings in demanding environments and soon became a trusted fixture in power generation and process plants. From that starting point, we have never stopped innovating. Over the decades we have developed infrared analysers for CO, CO2 and other gases, refined oxygen and moisture measurement for difficult applications, and built gas chromatography capability supported by complete sampling systems engineered around each application. Every analyser is calibrated against certified reference gases before it leaves our facility.
Today, TC Limited is recognised as a benchmark in high accuracy gas analysis, delivering complete analyser and sampling system packages to customers around the world from the UK.
Our Mission
At TC Limited, we exist to make precise gas analysis accessible and straightforward for industry. We know that accurate gas measurement directly impacts product quality, safety, regulatory compliance, operational efficiency, and environmental performance. Our job is to make sure you have the right analyser, correctly specified, supplied with a sampling system matched to your application, properly calibrated, and fully supported, from initial enquiry through to end of service life.
