CalSys Analyser Management software

Solution for analyser management and data acquisition

Unlock Operational Excellence with CalSys Analyser Management Software

CalSys is an analyser management and data acquisition system (AMADAS) using control charting techniques and statistical process control to determine the analytical performance, availability and maintainability of a broad variety of process analysers and other critical instruments. With its customisable features, integration capabilities, versatile accessibility, streamlined maintenance processes, availability summaries, statistical process control capabilities, enhanced validation options, user management functionalities, and efficient reference bottle management, CalSys enables organisations to achieve operational excellence. Thus, CalSys supports operators in achieving optimal efficiency in the maintenance of gas chromatographs, process analysers, gas detectors, CEMS, laboratory analysers and similar equipment, as well as optimising resources, improving decision-making, and driving productivity in industry-specific analytical processes.
