Product Description

GD-R2223 Automatic ISO6886 Oxidation Stability Tester

 

Introduction:

GD-R2223  Automatic ISO6886 Oxidation Stability Tester is manufactured in accordance with NB/SH/T 0873-2013 "Determination of Oxidation Stability of Biodiesel and Its Harmonic Fuels". Other applicable standards are as follows: NB/SH/T 0825, EN14112, EN15751, EN16568, ISO6886, GB/T 21121. The principle is that the sample is placed in a constant temperature aluminum heating block, and clean air is passed into the biodiesel sample, and the air flows through the sample into the measuring cell containing the absorption liquid and bubbling. The end of the induction period is accompanied by the production of a secondary reaction product, a volatile organic acid (mainly formic acid), which causes the conductivity in the measuring cell to accelerate. The conductivity of the absorbing liquid is recorded by the computer software, and the induction time is automatically obtained by automatically calculating the conductivity to the second-order differential maximum point of the time-varying curve.

 

Features:

1. The software automatically records the conductivity change curve and determines the induced inflection point by calculating the second derivative of the curve;

2. After the test is over, the result induction reaction time together with the test process curve will be stored in the database for query;

3. In addition to measuring the induced reaction time, the software also allows the evaluation of the so-called settling time, ie the conductivity required to reach a certain value.

4. The software can also re-evaluate each test curve. Select a section of the curve by setting the evaluation time range

Evaluate so that certain data anomalies due to cleaning, specimens or other reasons can be avoided;

5. The database can save all the data related to the test, including the conductivity curve, the induction reaction time, the method used,

Test start and stop time, etc.

6. Can query the test data by setting the query conditions;

7. The software also has the function of multi-curve comparison and curve analysis;

8. Display mode: curve / digital two modes

9. Calibration of temperature and flow can be performed by test software

10. Work unit: four tubes

11. Each sample is controlled separately, can be automatically set according to requirements.
