The manufacturer is no longer supporting the MIRAN SapphIRe as of 10/31/2020. CIH Equipment Company is here to help! We can calibrate, change the calibration date, and replace the filters for the discounted price of $495. NIST traceable calibrations are performed in our A2LA ISO 17025:2017 accredited laboratory. We offer a standard library check with N2O and SF6, calibration date reset, and 2 replacement filters (optional) at this time. Learn more about our MIRAN SapphIRe Calibration Lab.
