According to the test methods of GB/T503,GB/T5487,ASTMD2699,ASTMD2700 standard, it divides into the octane tester in motor method/research method.

Features

1.The instrument uses a computer LCD touch screen operation, which is a human-friendly communication interface

2.The screen interface can display real-time experimental parameters of the indicators change, for monitoring at any time

3.Automatic / jog operation adjust the compression ratio, with a limit protection

4.The Instrument uses the FLD modular designing, which can use two kinds of operation methods: interpolation and compression ratio method

5.The instrument can automatically generate test reports, and can automatically print the results

6.The instrument is equipped with SE air filtration system, it can provide standard, clean, dry and constant temperature gas;

7.The professional knock signal sensor FDT-DS uses the industry standard, it is more stable and reliable;

8.The instrument is equipped with a special Friend Company's knock detection system, which ensures that the knock signal of the zero, magnification, stable regulation of stability, the repeatability and precision of the instrument are less than 0.2 / R octane number.

9.The instrument uses a magnetic induction ignition, so that the ignition time in the test is more accurate.

10.The instrument is equipped with FAD security protection system, which is used for emergency protection under abnormal conditions to protect the safety of operators;

11.The instrument uses a user-friendly design, customers can also be based on demand, self-matching low-temperature test tank and cooling water circulation system.
