Water vapour in process gas is one of the most common causes of corrosion, product contamination, and process upsets. Even small amounts can damage pipelines, poison catalysts, form hydrates, or spoil the purity of an industrial gas. Measuring moisture accurately, and at the right range, is essential for dryness control and product quality. The best moisture analyser for your plant depends on your gas, your dew point range, and how the instrument will be used day to day. TC Limited manufactures moisture analysers for continuous process monitoring, portable checks, and trace measurement in very dry gases, and every analyser is supplied complete with a sampling system matched to your application.
