Flash Point Closed Cup Tester G-309
The Flash Point Closed Cup Tester G-309 is designed in accordance with the National Standard of the People’s Republic of China – Determination of Flash Point by Pensky-Martens Closed Cup Method (GB/T 261-2021), as well as ASTM D93 and ISO 2719-2002 standards. It adopts microprocessor control technology combined with a full-color touchscreen LCD system. The instrument is used to determine the flash point of liquid samples.
An additional ASTM D93 testing procedure is included for users requiring compliance with U.S. standards. This instrument is not suitable for low-temperature flash point testing. For low-temperature applications, model 309A intelligent low-temperature closed cup flash point tester is recommended.
The instrument features a Chinese-English bilingual menu and a full-color GUI touchscreen interface, providing intuitive display and simple operation. Users can quickly become familiar with operation without extensive reference to the manual. It offers fast testing speed, wide measurement range, good repeatability, and high accuracy.
The entire testing process is fully automatic. Parameters such as temperature and time are displayed on the LCD screen along with real-time working status and operation prompts. Users only need to preset the expected flash point or initial temperature. The instrument will automatically perform heating at a specified rate, ignition, flash point detection, lifting of the detection device, air cooling, and result printing.
It eliminates complex manual operations. The instrument supports both automatic atmospheric pressure detection and manual input. When automatic detection is active, manual input is disabled, and vice versa. Test results are automatically corrected according to atmospheric pressure variations.
The instrument includes powerful data processing capabilities, capable of storing up to 100 historical test results for review and printing. Preset parameters before shutdown are also retained. It features a built-in
perpetual calendar displaying year, month, day, hour, minute, and second. An optional RS232 interface is available for computer management (with software).
Instrument Structure:
The instrument features an integrated design with a compact structure, light weight, and small footprint. It incorporates a large-scale control core along with power supply circuits, interface circuits, clock circuits, driving circuits, and LCD display system. Key components include a heating furnace, lid opening mechanism, detection system, gas control valve, and lifting mechanism, enabling full automation of the testing process.
