Formaldehyde detector in water is widely used in environmental detection,wastewater monitoring and wa-ter pollution prevention.At present,there are no relevant verification regulations and calibration specifications.Therefore,in order to meet the traceability requirements of such instruments,a calibration method is proposed in this paper,and the uncertainty of the calibration indication error is evaluated.
