This instrument refers to NB/SH/T 0873-2013 "Biodiesel and its blended fuel oxidation stability determination accelerated oxidation
The Law stipulates manufacturing. Other applicable standards are as follows:
NB/SH/T 0825, EN14112, EN15751, EN16568, ISO6886, GB/T 21121
The measuring principle of the instrument is that the sample is placed in a constant temperature aluminum heating block,
and the clean air is passed into the biodiesel sample.The air flows through the sample into a measuring cell containing the absorbing liquid and bubbling.
The end of the induction period is accompanied by a secondary reaction product -The production of volatile organic acids (mainly formic acid)
will cause the conductivity in the measuring cell to accelerate. Absorbing liquid
Absorbing liquid The conductivity is recorded by the computer software and automatically obtained by automatically calculating
the second-order differential maximum point of the conductivity versus time curve.The induction time.
I. Main technical 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.Time required
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, It 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
