Brake fluid selection | According to GB12981-2003 Motor vehicle brake fluids, the brake fluid is divided into HZY3, HZY4, and HZY5. Corresponds to DOT3, DOT4, DOT5 internationally. There are different levels of brake fluid. The higher the level, the better the safety. In general, mini, mid-low grade cars are suitable for HZY3 standard brake fluid, while mid-high grade cars are recommended to choose HZY4 standard brake fluid. Of course, there is no problem in choosing HZY4 for mini, mid-low grade cars, and it is better. HZY5 standard brake fluid is mainly used in military industry, generally less used in civil, suitable for harsh conditions such as desert |

With the function of printing the test report and test pressure curve after the test is completed, the test report can be freely edited;
M. This system uses a high-frequency pressure sensor to achieve a high-speed boost rate, and its sampling frequency is high. In this way, through high-frequency sampling, the output pressure can be controlled more accurately and a smoother pressure output curve can be drawn;
N. The system also adds an abnormal pressure relief valve, which can more safely unload the internal high pressure of the system in the event of an abnormality in the system;
O. Adopt the company's self-developed dedicated control software, fully automatic control of the test process, automatic measurement, etc. It has the characteristics of good professionalism, high reliability, easy upgrade, etc., and can be upgraded and improved with the development of testing machine control technology and test standards;
P. The pressure drops rapidly after the test piece breaks, and the pressure stops automatically, that is, the equipment has the function of automatic shutdown protection after the test piece breaks, which ensures the safety of the person and equipment to the maximum extent, and is suitable for the test without any guard;
Q. For safety consideration, only can be pressurized when the test chamber safety door is closed;
R. There are transparent observation windows on the safety door of the test chamber, which can clearly observe and check the leakage and burst of the test pieces during the test;
S. The operation interface is simple and convenient, and the control software is updated and maintained easily.
T. The main electrical components are imported components, which guarantees the accuracy and stability of the testing machine from the control principle and the quality of the electrical components;
U. High-quality air-driven pumps and high-pressure control valves can ensure that the entire set of equipment can work for a long time without failure;
