Factory Calibration

LI-830, LI-850, and LI-870 recommended recalibration frequency: No regular factory recalibration required.

What's included with factory calibration?

A factory recalibration includes the following:

Calibration

  • Analyzer drift and stability is checked.
  • H2O analyzer calibration (6 points, 3 temperatures; LI-850 and LI-870 only).
  • 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 (LI-850 and LI-870 only).

Tests and Maintenance

  • The optical path components and hoses are inspected.
  • Software updated to the most recent version.
  • Other repairs and maintenance as needed; you'll be notified if additional repairs are required.
