Calibration Gas, Liquid Mixtures and Speciality Gas Mixtures

Our unique production methods and dedication to quality, combined with unparalleled service and support, have defined STAR as the standard for calibration. Wherever you are, whatever your application, you know you can rely on STAR. The composition of the mixtures available is practically infinite. It is restricted only by the physical and chemical properties, health, safety norms and the Stability and quality of the final mixture. At STAR we offer our clients any desired preparation tolerance and certification accuracy depending on the mixture components. We prepare mixture using highly accurate gravimetric / volumetric techniques traceable to National Physical Laboratory standard masses. We have advanced imported computerized gas chromatograph system, which enables higher accuracy and precision for each gas mixture.

These industrial gases and gas mixtures are made by gravimetric / volumetric methods complying with national & international standards & are traceable to NPL, India.
