Innovation point: Automatic determination system for gas moisture content: Traditional methods for measuring trace moisture content in gases in China mostly use manual control of the gas cylinder valve to allow gas to enter the Coulombic Karl Fischer titration cup for measurement. 875 KF is a fully automatic gas moisture determination system that integrates an injection valve, heating module, gas mass flow meter, Coulombic Karl Fischer titration instrument, and computer. Built in heating module: The pipeline is equipped with a heating module, which is not only suitable for pure gas samples, but also for gas-liquid mixed samples. The heating module can prevent moisture in the gas from condensing in the pipeline, ensuring that all moisture is transferred to the titration cup. Built in mass flow meter: Traditional methods use the balance weight reduction method to calculate gas mass, but gas cylinders are generally heavy, making it difficult to weigh with a precision balance and resulting in significant weighing errors. The built-in gas mass flow meter can accurately quantify the gas entering the Karl Fischer titration cup. Equipped with solvent cleaning function: suitable for gas samples containing oil, a solvent cleaning device can be configured to clean the entire system and pipeline to prevent oil contamination.
