Automatic Closed Flash Point Tester | VS-9806
Products Details
Closed flash point is an important safety and quality indicator for petroleum products and oil samples. It represents the lowest temperature at which vapor generated from the sample can form a flammable mixture with air and flash when exposed to an ignition source under specified test conditions. For oil storage, transportation, use, and maintenance, flash point data helps users evaluate volatility, contamination risk, and safe handling requirements.
The VS-9806 Automatic Closed Flash Point Tester is developed for automatic flash point determination in laboratory and industrial testing environments. It uses computer-controlled heating and temperature acquisition. During the test, the sample is placed in the test cup and heated according to the required rate. The instrument controls the opening, ignition, detection, and data processing process automatically.
The instrument adopts a color touch-screen interface with menu-based input. Users can enter parameters such as preset flash temperature, sample number, atmospheric pressure, test date, test time, and selected standard. The interface provides operation prompts, helping users complete setup more smoothly and reducing errors caused by manual operation.
During testing, the system scans temperature change, controls the heater through the internal control circuit, and performs ignition at the specified timing. When flash is detected, the instrument stops data collection, locks the flash temperature, closes ignition, stops heating, stores the result, and prints the test record. Atmospheric pressure correction can be applied by entering the local pressure value, which helps compensate for regional altitude differences.
The VS-9806 uses electronic ignition with a silicon nitride ignition head. The test arm can rise and fall automatically, reducing manual intervention around the hot test area. The system also includes automatic deviation correction, differential detection, and software prompts for incorrect operation. These functions make the instrument practical for laboratories that require clear test workflow and stable records.
The tester is widely used in petroleum product inspection, power transformer oil testing, railway and aviation oil testing, industrial lubricant monitoring, and scientific research. It is suitable for organizations that need a benchtop automatic closed cup flash point tester for routine quality control and safety assessment.

Product Guide
Before testing, place the VS-9806 in a clean environment without corrosive gas. Check the instrument, accessories, power cable, ground wire, oil cup, fuse, and printer paper before use. The test cup should be cleaned with petroleum ether before adding a new sample, especially when switching between different oil products.
Connect the power cable to the AC 220 V supply and turn on the instrument. After entering the system through the touch screen, the operator can run the self-check interface and raise the test arm. The cleaned test cup is filled with the oil sample to the specified mark, then placed into the heating bath. After that, the test arm is lowered automatically to the lower position.
Before starting the test, enter the required parameters on the screen, including preset flash temperature, sample number, atmospheric pressure, and test standard. Atmospheric pressure input is important because different altitude conditions can create relative deviation in flash point results. The instrument can automatically correct the effect of atmospheric pressure and calculate the corrected value.
After the test begins, the VS-9806 automatically heats the sample, controls the ignition timing, opens the cover, detects flash, and monitors temperature. When flash occurs, the system locks the flash point temperature, stops heating, turns off electronic ignition, stores the related data, and allows the result to be printed.
Users can enter the record review page to check historical results. The previous and next page keys allow the operator to browse saved records, and the output key prints the selected content. For routine laboratory use, this helps maintain traceable records for oil sample testing.
To protect the heating system, the instrument should not be started without oil in the test cup. The lifting mechanism should not be forced manually. Between two oil sample tests, the manual specifies a 15-minute interval to avoid errors in heating rate calculation.

Customer Case
A transformer maintenance laboratory needed to evaluate flash point together with other oil condition indicators for oil samples collected from several substations. The laboratory wanted a more automated method because manual testing required close attention during heating and ignition, and the staff needed consistent printed records for each sample.
The laboratory used the VS-9806 Automatic Closed Flash Point Tester for routine closed cup flash point measurement. Before each test, the technician cleaned the oil cup, added the sample to the specified mark, entered the sample number and atmospheric pressure, and selected the required test settings from the touch screen.
During the test, the instrument automatically controlled heating, cover opening, electronic ignition, and flash detection. When the flash occurred, the system locked the temperature and stored the result. The technician then printed the test record and added it to the oil sample file together with moisture, acid value, and dielectric strength results.
The automatic workflow reduced manual intervention and helped the laboratory maintain clearer records. The customer used the flash point data to identify oil samples requiring closer review before reuse or continued service.
