Designed to meet GB/T 6536 and ASTM D68 requirements, this apparatus is used for distillation analysis of natural gasoline (stable light hydrocarbons), motor gasoline, aviation gasoline, jet fuel, special boiling point solvents, naphtha, kerosene, diesel, gas oil distillate fuels, and similar petroleum products.
Integrated automation
The instrument employs a multi-threaded control system, centralizing operation, monitoring, calculation, and result display on a 10.4‑inch full‑color Chinese touchscreen – eliminating manual intervention and improving repeatability.
High‑precision sensing & optical detection
Imported temperature sensors ensure accurate thermal control.
A digital optical detection system reads the graduated cylinder, eliminating parallax errors.
Fiber‑optic sensing technology, combined with a step motor that precisely tracks the liquid level, allows real‑time volume measurement during distillation.
Real‑time visualization & smart control
During the test, all relevant parameters and live distillation curves are shown dynamically on the screen. The cold bath and receiver chamber temperatures are intelligently controlled, strictly following standard test methods. Both initial boiling point (IBP) and final boiling point (FBP) are reliably determined.
Automated end‑point judgment & data management
The system automatically determines the end of distillation. Results can be displayed, printed, and traced. Additional automation includes:
Automatic atmospheric pressure correction (no manual calculation needed)
Automatic flame control for safety
Fault protection – the system alerts and shuts down if abnormalities occur
Safety
A built‑in nitrogen fire extinguishing system immediately suppresses any flame inside the apparatus, ensuring operator and laboratory safety.
