In the fast-paced worlds of petroleum, chemical engineering, power generation, and environmental protection, reliable flash point testing is non-negotiable for safety, quality control, and regulatory compliance. Introducing the YH-261B Automatic Closed-Cup Flash Point Tester—a cutting-edge solution engineered to meet the strictest global standards, including China’s GB/T261-2008 (Pensky-Martens Closed-Cup Method), SH/T0315, ASTM D93,and international ISO2719. Designed for laboratories and facilities across oil refineries, railways, research institutions, and more, this instrument redefines efficiency, accuracy, and user-friendliness in closed-cup flash point analysis.
At the heart of the YH-261B’s performance lies its advanced control system: a new-generation high-speed signal processor paired with an adaptive PID algorithm. This dynamic duo automatically adjusts the heating curve to align with standard requirements, eliminating manual errors and ensuring consistent thermal conditions—critical for reliable flash point detection. Complementing this is a built-in atmospheric pressure sensor that continuously measures ambient pressure, automatically corrects deviations, and adjusts flash point values in real time. No more manual calculations or guesswork; the YH-261B adapts to environmental changes, guaranteeing precision even in fluctuating lab conditions.
Automation is another standout feature, streamlining the entire testing workflow from start to finish. The instrument handles all key tasks autonomously: sample elevation, stirring, ignition, flash point detection, alarm triggering, cooling, and result printing. This not only saves valuable labor time but also minimizes human intervention—reducing the risk of operational mistakes. Safety is prioritized too: instead of risky gas-based ignition, the YH-261B uses a gas-free platinum alloy heating wire, delivering stable, reliable ignition while eliminating fire hazards. It also includes differential detection technology to auto-correct system deviations and an over-temperature protection mechanism that shuts down testing and sounds an alarm if temperatures exceed safe limits—safeguarding both operators and equipment.
The YH-261B’s technical specifications further reinforce its credibility for global use. It features a 10-inch touchscreen display with both Chinese and English interfaces, making it accessible to teams worldwide. The thermocouple differential detection method ensures precise temperature sensing, with a measurement range of room temperature to 400°C—covering the flash point needs of nearly all petroleum products, from light fuels to heavy oils. Temperature resolution is 0.1°C, enabling ultra-fine monitoring, while repeatability meets both national and international standards: for flash points <104°C (GB) or ≤110°C (ISO), the allowable error is ±1°C; for higher values, it is ±2°C. A low-power, high-speed thermal printer (56mm paper width) delivers instant test reports, and a self-diagnosis function automatically identifies faults—simplifying maintenance and reducing downtime.
Data management and future-proofing are also addressed: the YH-261B stores up to 2000 test results for easy historical query, supporting compliance audits and trend analysis. When industry standards are revised, the instrument’s program can be upgraded—ensuring it remains compatible with the latest regulations and extends its service life. For post-test efficiency, a forced air cooling system rapidly lowers the instrument’s temperature, enabling faster sample turnover for high-volume labs.
Whether you’re a refinery validating fuel safety, a chemical plant monitoring product stability, or a research team conducting advanced petroleum analysis, the YH-261B Automatic Closed-Cup Flash Point Tester combines precision, automation, and compliance to meet your most demanding needs. It’s not just an instrument—it’s a reliable partner for global petroleum testing excellence.
