Your MIRAN Analyzer will undergo calibration that covers the full infrared range of the instrument. We use either NIST traceable gases or depending on the model, injection of a known quantity of liquid that is immediately transformed to vapor in the process. We have the means and know how to change the calibration date on your analyzer so that there is no confusion as to if or when it was calibrated. CIH Equipment is an A2LA Accredited ISO 17025-2017 laboratory using the good standard metrology calibration practices under our quality control system.
