The series of fully automatic distillation range testers launched by Shandong Hengmei Electronic Technology Co., Ltd. integrate advanced sensing technology and intelligent control systems, with excellent measurement performance and reliable operational stability. We are committed to providing accurate and efficient detection tools for users in the petrochemical industry through professional fully automatic distillation range measuring solutions, helping to improve product quality and technological innovation.

Technical principle
The fully automatic distillation range analyzer is based on the principle of the difference in boiling points of different hydrocarbon compounds, and achieves automated determination of distillation range characteristics through precise control of heating, condensation, and distillate collection processes. The core workflow is as follows:
Sample loading and initialization
Take 100mL of the sample and inject it into a standard distillation flask, then install it into the heating furnace
The instrument automatically detects the liquid level and sets the condensation bath temperature (adjustable from 0-60 ℃)
Program heating and distillation
The heating furnace is precisely controlled for heating rate according to standard requirements (room temperature -500 ℃)
German JUMO original PT100 temperature sensor for real-time monitoring of steam temperature (0-400 ℃)
Infrared optical detection system accurately captures every drop of distillate
Distillate collection and data recording
Semiconductor refrigeration system ensures stable condenser tube temperature (-20-70 ℃± 1 ℃)
High precision volume sensor for real-time monitoring of distillate volume (0-100mL, resolution 0.01mL)
Automatically record the temperature values corresponding to the initial boiling point, final boiling point, and specific recovery rate
The measurement process strictly follows national standards such as GB/T 7534 and GB/T 3146.1 to ensure the accuracy and comparability of the data.

Industry pain points and solutions
Pain point one: Traditional manual operation has large errors
Artificial error: The subjectivity of endpoint judgment is strong, and there is a visual error in temperature readings
Solution: The fully automatic distillation range analyzer uses infrared optical detection and precision temperature sensing to automatically determine the endpoint and eliminate the influence of human factors
Pain point 2: Low experimental efficiency
Traditional dilemma: A single measurement can take up to 1-2 hours and requires dedicated personnel to be on duty
Solution: Fully automated process with unmanned operation, parallel processing of multiple tasks, increasing efficiency by over 50%
Pain point three: Poor comparability of data
Standardization issue: large data deviation between different operators and laboratories
Solution: Standardized program control to ensure consistent measurement conditions and data repeatability error<0.5%
The fully automatic distillation range analyzer has successfully solved the technical difficulties in traditional distillation range determination through precise temperature control, automated distillate detection, and intelligent data processing. The high-precision and reproducible distillation range data it provides has become an important technical support for quality control, process optimization, and new product development of petroleum products.
