SH105B Automatic Closed Flash Point Tester GB/T261‑2021 Oil Petroleum Measuring Printing Function

SH105B Automatic Closed Flash Point Tester GB/T261‑2021 Oil Petroleum Measuring Printing Function

The SH105B Fully Automatic Closed Cup Flash Point Tester is built with microcomputer control and a large LCD screen. Following standard test procedures, the instrument automatically completes heating, cup lifting, ignition, flash point detection, value locking and result printing. It will initiate automatic cooling once the test finishes, delivering fully automated operation. This tester is widely applied in electric power, petroleum, chemical, commodity inspection and research laboratories. It conforms to ISO 2719, ASTM D93 and GB/T261-2021.

Flash point

Under the specified test conditions, the test flame causes the sample vapor to ignite and spreads the flame to the lowest temperature on the liquid surface, corrected to 1013kPa atmospheric pressure.

Standard: GB/T261-2021 ASTMD93

Technical performance parameters:

A. Step B and C conversion

This instrument features a large color LCD screen, full Chinese HMI dialogue interface and membrane keypad.
It automatically detects atmospheric pressure, calculates correction values and compensates for the pressure influence on test results.

The entire test sequence including cup opening, ignition, flash point detection and data printing runs automatically, with automatic lifting and lowering of the test arm.
It adopts electronic ignition and forced air cooling; no external gas supply is required.

- Printer: Built-in micro thermal printer
- Pressure sensing: Integrated atmospheric pressure sensor for automatic pressure correction
- Safety advantage: Gas-free automatic ignition enhances test safety
