An accurately calibrated instrument is crucial in complying with the requirements of regulatory groups like the FDA. Without properly functioning chart recorder systems, maintaining consistency in product quality is not possible. Environmental conditions may also affect the functionality of your instruments. Exposure to dust or dirt, vibrations, shocks, as well as any other external forces affecting chart recorders during storage or application increases the need for routine calibration. In the event of an audit, you should feel confident in the accuracy of your instruments and the overall quality of your product.
