Summary:
QX-C dual-purpose gasoline and diesel tester is a special instrument used for measuring octane number of gasoline (including aviation, national standard, blending, ethanol) and cetane number of diesel oil in petroleum refining and chemical enterprises. The instrument USES a large screen display (108 x 42), the back light is bright and soft, the interface font is clear, with: easy to operate, fast measurement speed, high precision, wide range and other characteristics. The instrument has four technological innovations: 1. The sensor adopts digital transmission technology. Strong anti-interference ability, small variation, high precision; Reproducibility, good repeatability. 2. The scanning program of the instrument adopts mathematical model, and values of parameters A and K can be automatically calculated and assigned after calibration. The calibration results are accurate and reliable. 3. The determination procedure can be automatically returned. The ASTM--CFR test machine determination results are taken as the standard, and the targeted regression is carried out to improve the determination accuracy and expand the determination range. 4, the aviation gasoline, automotive gasoline, blended gasoline, ethanol gasoline, automotive diesel through the first regression can be done by a key determination.
Four technological innovations: digital sensor, automatic valuation and calibration, automatic regression, one-key measurement, using humanized design, easy to operate, improve the measurement accuracy of the instrument, expand the scope of use of the instrument, convenient for customers, show the practical value of the instrument.
Working principle:
The gasoline octane number determination principle is according to the national standard GB/T5487, USES the ASTM - CFR test machine to realize, is also internationally recognized. It is measured by comparing reference fuel with standard engine with variable compression ratio under strict test conditions. QX series measuring instrument is used to determine the comprehensive dielectric constant of oil components. Is based on rigorous mathematical model for regression theory, by means of advanced electronic measurement technology, on the basis of CFR tester determination results, targeted for automatic regression, the corresponding measurement range can ensure measurement accuracy, broke through the quantity cannot dissemination, has realized the CFR tester dissemination of QX series apparatus.
