Gasoline Oxidation Stability Tester (Induction period method) ASTM D525

Standard:

GB/T 8018

ASTM D525

Performance characteristics

1.       The whole process of the experiment is automated, no personnel is required to be on duty, and the result is automatically judged;
2.       PLC control, 7-inch color LCD touch screen;
3.       The stainless steel automatic pressure relief valve of the body handle is designed by the national patent; automatic temperature control, oxygenation, judgment of oxidation turning point and end of the experiment;
4.       The experimental results can be stored, deleted, consulted, printed, and downloaded.
5.       Optional LIMS system association component.
6.       Desktop integrated machine, compact and reasonable structure.
7.       Metal bath body, clean and tidy. The altitude of the environment is high and low. The atmospheric pressure does not affect the temperature control of the instrument (water at high altitudes will decrease due to atmospheric pressure and low boiling point, and will boil at less than 100 °C).
8.       High-precision PLC programmable controller is the core of the instrument's control system.
9.       Temperature control is accurate and stable.
10.     National utility model patent (patent number: ZL201621447589.0) designed non-disposable pressure relief valve, automatic pressure relief when the internal pressure exceeds 1500kpa, to ensure the safety of the experimenter and instrument. The pressure relief valve automatically returns to the initial state after the pressure relief.
11.     The pressure inside the test oxygen bomb is monitored in real time by a high-precision pressure transmitter and displayed on the operation screen. The operator can know the pressure inside the experimental bomb anytime and anywhere.
12.     The instrument automatically records the test time and real-time pressure value, automatically determines the occurrence of the turning point (ie, the induction period), and records this time.
13.     The program has a command to judge the leak. If the test body leaks, the instrument will prompt the user to invalidate the test.
14.     Users can set the test according to their own needs and how long to stop the test.
15.     The instrument will automatically cut off the heating power after the test is stopped to ensure safety. In addition, a temperature switch of 120 °C is installed in the metal bath. When the bath temperature exceeds 120 °C, the instrument will automatically cut off the heating power. Double protection and higher security.
16.     The instrument can automatically charge and discharge oxygen (first charge and replace oxygen air replacement, then re-charge the oxygen pressure to the required pressure value).
17.     It can be manually charged and discharged, and the pressure value in the test bomb is artificially fine-tuned.
18.     The oxygen release rate can be adjusted by the precision valve on the side of the instrument.
