In industries such as petroleum, chemical, and power, as well as in the fields of scientific research and quality inspection, safety has always been the sword of Damocles hanging above our heads. When it comes to flammable liquids, a key safety indicator - the closed flash point - becomes the core parameter for measuring their storage, transportation, and use risks. The fully automatic closed flash point meter is a modern and precise equipment for accurately measuring this key indicator.
Core mission: Accurately capture "dangerous critical points"
Closed flash point is defined as the lowest temperature at which a mixture of vapor and air formed by a liquid under specific sealed conditions can instantly ignite (but not sustain combustion) when exposed to an open flame source. This temperature value directly reflects the potential fire and explosion risks of liquids in enclosed spaces. The core task of the fully automatic closed flash point analyzer is to strictly follow the international (ISO 2719:2016) and national (GB/T 261-2021) standards to achieve highly automated, accurate, and reliable determination of this critical temperature.
Intelligent operation: precise control and sensitive capture
The working principle of the instrument embodies the perfect combination of intelligence and precision control:
Programmed heating: The instrument has a built-in program that strictly heats the sample according to the standard heating curve (providing three rate options: A: 5-6 ℃/min, B: 1.0-1.5 ℃/min, C: 2.5-3.5 ℃/min).
Automatic ignition and detection: When the temperature approaches the expected flash point, the instrument automatically performs electric ignition. The K-type thermocouple serves as a sensitive "eye" to constantly monitor small temperature changes inside the test cup.
Instantaneous capture and locking: Once the sample vapor is detected to flash, the instrument instantly locks the temperature value at that moment.
Intelligent cooling: After the test is completed, the fan automatically starts to quickly cool the heater and improve the testing efficiency.
The results show that the measured flash point value is displayed clearly on the 7-inch high-definition Android touch screen (1024 * 600 pixels) in real-time, and a complete report containing temperature curves, Chinese characters, graphics, and even QR codes is output through the built-in thermal printer.
Hard core strength: excellent performance lays a reliable foundation
The technical parameters of this instrument fully demonstrate its reliability as a professional measurement tool:
Wide measurement range: from room temperature to 400 ℃, covering the vast majority of petroleum products and chemical solvents.
Top temperature sensing: using A-grade PT100 platinum resistance temperature sensor (three wire system, with temperature compensation), the detection accuracy is as high as 0.1 ℃, and the overall accuracy is ± 0.5 ℃.
Accurate correction of air pressure: Equipped with a high-precision air pressure gauge (≤ 0.5kPa), ensuring that the results are not affected by fluctuations in environmental air pressure.
Excellent repeatability: When the closed flash point is ≤ 110 ℃, the repeatability is ≤ 3.0 ℃; >At 110 ℃, ≤ 5.0 ℃ ensures stable and reliable results.
Intelligent temperature control and robust design: The intelligent temperature control algorithm ensures precise heating; 6.4mm thick air bath provides a uniform and stable heating environment.
Powerful data management: Data storage space is only limited by the built-in EMMC capacity, supporting data export to USB flash drives or uploading to cloud platforms for easy traceability and management.
Comprehensive self inspection guarantee: Automatically detect the status of the lifting arm, ignition wire, printer, fan, and switch cover when turned on, ensuring that the equipment is always in the best working condition.
Ubiquitous security guards
The application scenarios of fully automatic closed flash point tester are wide and critical:
Petrochemical: Accurately determine the flash point of gasoline, diesel, kerosene, lubricating oil, fuel oil, solvent oil, asphalt and other products to ensure compliance with safety regulations.
Chemical production: Monitor the fire hazards of various organic solvents, paints, coatings, resins, plasticizers, and other chemical raw materials and products.
Electric energy: Evaluate the safety of key oil products such as transformer insulation oil and turbine oil during operation.
Quality inspection and commercial inspection: As a third-party organization, we conduct product quality supervision and import/export inspection in accordance with national/ISO standards.
Research and development: Evaluate the safety performance of new materials and new energy sources (such as biodiesel) in their research and development.
Hazardous chemical management: providing core data support for the safe storage, classification labeling (such as GHS), and transportation conditions of flammable liquids.
Core Value: From Accurate Data to Intrinsic Safety
The value of a fully automatic closed flash point meter goes far beyond providing a temperature value:
Accident prevention: By accurately identifying the minimum ignition temperature of flammable liquids, scientific basis is provided for formulating fire and explosion prevention measures, effectively preventing fire and explosion accidents.
Compliance assurance: Ensure that the product fully complies with national and international safety standards and meets regulatory requirements.
Quality control: Flash point is an important quality indicator for many petroleum and chemical products, directly related to their purity and performance.
Improving efficiency: Automated operations significantly reduce the intensity of manual operations and the risk of errors, improving testing efficiency and laboratory productivity.
Data Traceability: Powerful storage, export, and printing functions provide complete and reliable basis for quality records, accident analysis, and product certification.
The fully automatic closed flash point analyzer, with its highly automated, precise, reliable, easy to operate, and powerful features, has become an indispensable safety "gatekeeper" in modern industrial laboratories. It is not only a cold machine, but also transforms invisible steam risks into clear and readable safe temperatures, silently guarding every link from production lines to storage tanks, from laboratories to terminals. While pursuing efficiency and development, this precision instrument constantly reminds us that safety begins with a precise understanding and awe of the critical points of danger. Every precise test is contributing an irreplaceable force to building a safer industrial environment.
