Automatic Open Flash Point Tester | VS-9806A
Products Details
Open flash point is an important indicator for petroleum products and oil samples. It shows the temperature at which vapor from the sample can ignite briefly in open cup test conditions. For oil storage, transportation, equipment maintenance, and quality inspection, flash point data helps users evaluate volatility, contamination by lighter fractions, and safe handling requirements.
The VS-9806A Automatic Open Flash Point Tester is developed for automatic open cup flash point analysis. It uses an ARM series microprocessor, electrically erasable memory, a 7-inch color LCD touch screen, and PID self-tuning control. The instrument controls the heating curve according to GB/T 3536-2008 and GB/T 267-88 method requirements and displays sample temperature, set values, test status, pressure data, and flash point results during operation.
Unlike gas ignition systems, the VS-9806A uses electric ignition and does not require combustible gas. When the sample temperature approaches the expected flash point, the CPU controls the electric ignition system and automatic sweep movement. Once flash is detected, the instrument locks the flash point value, stops heating, saves the result, prints the record, and starts forced air cooling for the heater.
The system provides four main interface areas: sample testing, system self-check, system setting, and historical records. In the setting interface, the operator can select the test standard, enter the preset flash point, sample name, operator name, print setting, print mode, and time. The historical record interface allows users to browse stored test results, clear stored records, and print selected records.
The VS-9806A can store up to 1000 measurement results and includes a real-time clock with power-off retention. Automatic atmospheric pressure detection and correction help reduce the influence of pressure variation on test results. Temperature over-limit detection can stop testing automatically and provide alarm prompts.
This instrument is suitable for laboratories that need stable open cup flash point testing with automatic heating, ignition, detection, cooling, printing, and record management. It is used in petroleum, power, chemical, inspection, and industrial oil testing applications.

Product Guide
Install the VS-9806A on a stable workbench that is not exposed to direct sunlight or strong air flow. The manual recommends using the instrument in a fume hood, but the fan should not be turned on during sample testing because air flow can affect the flash point result. The instrument should be connected to a 220 V, 50 Hz single-phase AC power supply, with voltage fluctuation not greater than 5%; a 1000 W AC stabilizer can be used when needed.
After power-on, the lifting rod rises automatically and the instrument displays the startup interface. The operator can enter the sample test interface, system self-check interface, system setting interface, or historical record interface from the touch screen. Before formal testing, the self-check functions can be used to verify lifting rod movement, sweep rod movement, electric ignition, fan operation, flash detection, and printing.
In the system setting interface, select the required test standard, such as GB267-88 or GB3536-2008, then set the preset flash point, sample name, operator, print status, print mode, and time. The preset flash point helps the instrument control the test process and determine when ignition should begin.
Pour the sample into the open cup according to the expected flash point. Samples below 210°C should be filled to the upper mark, while samples above 210°C should be filled to the lower mark. Place the sample cup on the heater, enter the sample test interface, and press start. The lifting rod drops automatically and the test begins.
During testing, the instrument heats the sample according to the standard method curve. When the sample temperature approaches the flash point, the electric ignition system starts and the ignition rod sweeps automatically. When flash occurs, the instrument locks the flash point value, raises the lifting rod, displays the result, prints the record, saves the data, stops heating, and starts forced air cooling.
After testing, remove the sample cup only after the cup and heater have cooled. Clean the open cup before changing samples. The flash sensor should be cleaned carefully with gasoline or petroleum ether if oil contamination accumulates, because contamination may affect detection accuracy.

Customer Case
An industrial oil testing laboratory needed to test open flash point for multiple lubricant and insulating oil samples. The previous workflow used manual observation and required additional preparation for ignition, making testing slower and more dependent on operator experience.
The laboratory used the VS-9806A Automatic Open Flash Point Tester to standardize the process. Technicians selected the test standard, entered the preset flash point and sample name, filled the sample cup according to the expected flash point range, and started the test from the touch screen.
The instrument automatically controlled heating, electric ignition, sweep movement, flash detection, result locking, printing, storage, and cooling. The automatic atmospheric pressure correction helped the laboratory keep results more consistent across seasonal pressure changes.
After implementation, the laboratory used stored records and printed reports for customer documentation. The automated workflow reduced manual observation work and helped technicians maintain a more repeatable open flash point testing process.
