The physics goal of the Jiangmen Underground Neutrino Observatory (JUNO) is mainly to determine the neutrino mass hierarchy by precisely measuring the oscillation spectrum with 3%/Evis(MeV) energy resolution.Totally, about 20, 000 large area 20” tubes with high photon detection efficiency will be used to achieve this requirement, including 5,000 Hamamatsu dynode PMTs and 15,000 NNVT MCP PMTs. The JUNO collaboration has built two systems to check the performances of these tubes, which have been running since July 2017 and about 14000 tubes have been tested, so far. The key parameters compared with vendor data, including operating voltage, photon detection efficiency, dark count rate, rise time, fall time are presented. The selected PMTs meet all the requirements of the JUNO detector.
