Abstract： Based on the measurement principle of the urea detector， this paper proposes a method to test the performance of the urea detector， mainly to detect its wavelength and concentration indication error， and to evaluate the uncertainty of the test results. This test method has been verified by experiments， and the results are accurate and reliable.
