Abstract：A calibration method of ozone concentration in ozone aging test chamber was proposed, and the uncertainty of indication error of ozone concentration was evaluated. It was verified by experiments that the indication error of ozone concentration in the calibrated ozone aging chamber was less than ±10%, the position deviation of ozone concentration was less than 20%, and the fluctuation of ozone concentration was less than ±10%. It effectively solved the problem of traceability of ozone concentration in the ozone aging chamber, and improved the accuracy of the equipment test.
