? 1. The device can flow switches and pressure switch life test. 2. System test pressure is adjustable from 0 to 1MPa, flow 0 ~ 10L / min adjustable. 3. Test requirements: equipment so that the test product water power, water power cycle work. Water passage time and without water time is adjustable from 0 ~ 9999S respectively. 4. Timing testing requirements: When life test every certain number n, the machine may contact resistance of the sample, start the flow, pressure and shut the flow starts, turn off the pressure and automatic test data recording. n from 0 to 999999 can be set, power-down can remember. (E.g., n = 500, i.e., each life test conducted 500 times, to conduct a performance test) 5. Periodic testing of the project: start flow, and shut the flow (flow switch), starting pressure, closing pressure (pressure switch), contact resistance. And pre-test data were compared. 6. It can be set to stop the number of tests (such as the number of tests is set to 1000, the test to stop testing after 1000 and paragraph (3) of the test item test.); 7. During the test, when the detected unqualified project, immediately stop the test and alarm. 8. Test station: 4 9. Test data can be printed. Guangzhou Sea Test Equipment Co., Ltd Contact person:???
