LI-7200/RS Factory Calibration

Recommended Recalibration Frequency for the LI-7200 and LI-7200RS: Every two years; however, if the internal chemicals are serviced every two years and the analyzer zero and span are verified, then no regular factory recalibration is required.

What is included with factory recalibration?

A factory recalibration includes the following:

Calibration

  • Analyzer drift and stability is checked.
  • H2O analyzer calibration (6 points, 3 temperatures).
  • CO2 analyzer calibration (13 gas concentrations at 3 temperatures).
  • The accuracy of the calibration function is then verified across the measurement range of CO2 and H2O.
  • Pressure transducer calibration.
  • Temperature sensors verification.
  • Flow module verification and calibration as needed.

Tests and Maintenance

  • Clean analyzer, if needed.
  • Replace all internal chemicals.
  • Checked for leaks and repaired as needed.
  • Lithium coin cell battery changed as needed.
  • Upgrade software to the most recent version.
  • Other repairs and maintenance as needed; customers are notified if additional fees are required for repairs.
