This instrument completely overcomes the drawbacks of traditional manual flash point testing, which relies on manual observation and suffers from high error rates, by establishing a standardized and automated testing process.
- Preparation: Install the instrument in a fume hood free from direct sunlight and air convection (turn off the fan during testing), and connect it to a stable power supply. Upon startup, the instrument automatically performs the reset of the lifting rod and system initialization, displaying a welcome interface.
- Parameter Settings: Enter the system settings interface, select the testing standard (GB/T 3536-2008 or GB/T 267-88), enter the preset flash point value, sample name, and operator information, and configure the printing mode (簡 print / full print).
- Sample preparation: Pour the test liquid into a standard Cleveland open cup. For samples with a flash point below 210°C, add the liquid to the upper calibration mark; for samples above 210°C, add it to the lower calibration mark. Place the sample cup steadily on the heater.
- Automatic Testing: Return to the sample testing interface and click the "Start" button. The lifting rod automatically drops, and the instrument begins heating according to the temperature rise curve specified by the national standard. When the sample temperature approaches the preset flash point, the system automatically controls the ignition rod to perform a horizontal sweep.
- When a flash ignition phenomenon is detected, the instrument immediately locks the flash point value, automatically stops heating, and activates the air cooling system, while printing the test report and saving the data. Upon completion of the test, the lifting rod automatically rises, allowing the next test to proceed after cooling.
With its outstanding performance and reliability, this instrument meets the requirements of various industries for flash point testing of flammable liquids.
- Oil Industry: Determining the flash points of heavy oil products such as lubricating oil, gear oil, hydraulic oil, heavy fuel oil, and asphalt to ensure safety during production, storage, and use.
- Power Industry: Determine the flash point of insulating oils such as transformer oil to promptly identify equipment insulation aging issues and prevent power accidents.
- Chemical Industry: Assessment of fire hazards associated with chemicals such as resins, paints, coatings, and high-boiling-point solvents
- Commercial Inspection and Quality Inspection: Used for quality inspection of imported and exported oil products and chemical products to ensure compliance with national safety standards.
Addressing the pain points in traditional open-flame flash point testing, this instrument offers a targeted solution:
Solution: Utilizing high-sensitivity photoelectric flash detection technology to replace manual visual inspection, the system can accurately capture instantaneous flash ignition signals and eliminate subjective judgment discrepancies. The instrument is equipped with a built-in PID self-regulating temperature control system that strictly adheres to national standard heating curves, ensuring consistent test results for identical samples.
Solution: The instrument is designed with a wind-resistant structure, and the fan must be turned off during testing within the fume hood to minimize airflow interference. It incorporates an integrated atmospheric pressure sensor that automatically detects local air pressure and adjusts test results accordingly, ensuring measurement accuracy across different altitude regions.
Solution: Equipped with a comprehensive system self-test function, it enables independent testing of the operational status of components such as the lifting rod, ignition rod, ignition wire, and fan, allowing rapid fault localization. The instrument requires no complex daily maintenance; only periodic cleaning of oil contaminants on the flashover sensor with gasoline or petroleum ether is necessary.
Solution: Equipped with a high-capacity built-in storage unit capable of storing 1,000 test records. Each record includes sample name, preset flash point, measured flash point, test date, atmospheric pressure, and operator information. The system supports sequential querying and printing of individual records, as well as batch data export, meeting laboratory quality management requirements.
The introduction of this fully automated open-mouth flash point tester fills the market gap for mid-to-high-end flash point testing instruments in China. Its performance specifications match those of international counterparts, while its price is only about one-third of imported products, significantly reducing testing costs for enterprises. Additionally, the fully automated operation process minimizes human interference, enhancing the accuracy and reliability of test results, thereby providing robust technical support for production safety and quality control across various industries.
Currently, this product has passed the testing and certification by national authoritative institutions and is officially available for sale nationwide. It will be widely used in oil safety testing processes across various laboratories, quality inspection centers, and manufacturing enterprises.
