The SH6536A Fully‑Automatic Dual‑Tube Distillation Range Tester features a color LCD display with Chinese‑language menu for human‑machine interaction and wizard‑guided operation. The complete test procedure runs fully automatically.

Engineered and manufactured to meet GB/T 6536 (Test Method for Distillation of Petroleum Products), ASTM D86, GB/T 7534‑2004 (Test Method for Distillation Range of Industrial Volatile Organic Liquids), GB/T 3146‑1982 (Test Method for Distillation Range of Benzene Products), GB/T 18255 (Test Method for Distillation Range of Coking Viscous Oil Products), GB/T 26984 (Test Method for Distillation Range of Crude Oil), and GB/T 615‑2006 (General Test Method for Distillation Range of Chemical Reagents). It also complies with standard distillation‑range test requirements for methanol and other alcohol‑based products.

This instrument is suitable for chemically‑stable organic liquids under atmospheric distillation conditions, including hydrocarbons, esters, alcohols, ketones, ethers and analogous compounds. It is widely deployed for distillation‑range measurement of petroleum products, industrial volatile organic liquids and organic solvent raw materials.

Built‑in embedded system together with an imported industrial control unit and large‑size touch LCD delivers an intuitive user interface for effortless operation. Powered by single‑chip microcomputer and intelligent control technology, the full distillation workflow is performed automatically: heating and cooling, distillate liquid‑level tracking, distillation‑rate regulation, recovered‑volume monitoring, temperature logging and result print‑out.

Main Performance Characteristics

Second, functional characteristics

• The instrument by the industrial computer automatic measurement and control test process, full touch 10.4 inch LCD display test,
• Display temperature and volume data and related curves throughout the process.
• The liquid level tracking system is composed of high subdivision step American linear motor and imported photoelectric tracker.
• Cold tube temperature, measuring cylinder chamber temperature, using mechanical refrigeration, compressor for foreign famous brand manufacturers. Internal circulation of the cooling medium.
• Cooling water can be added once every 3 years.
• Electric distillation furnace heating automatic control, so that the sample from the initial distillation point to 95% of the flow rate, control within 4 ~ 5ml per minute.
• Can provide the initial and final distillation point temperature value, can provide the temperature value of each percentage point and flow rate.
• Automatic detection of local atmospheric pressure, automatic correction to the standard atmospheric pressure temperature.
• You can choose to stop the test according to steam temperature or recovery volume.
• The instrument can store, query, print test results.

III. Technical parameters

• Temperature range: room temperature ~ +400°C accuracy ±0.1°C
• Display accuracy: 0.1℃ steam temperature sensor: Germany import PT100 platinum resistance
• Start heating to the initial distillation point: 5 ~ 15 minutes
• Distillation rate (flow rate from initial distillation point to 95% recovery) : 2 ~ 10ml/min (adjustable)
• The remaining amount of 5ml in the flask to the end point: no more than 5 minutes
• The temperature of the initial distilling point is detected by the optical fiber sensor
• Recovery volume measurement range: 0 ~ 100ml
• Measuring accuracy of recovery volume: ± 0.1ml
• Volume measurement: liquid level tracking system, mainly composed of stepper motor and optical fiber liquid level sensor, motor step 0.01ml each time
