Description
Overview
The UHV-650 Automatic Closed‑cup Flash Point Tester determines closed‑cup flash points of transformer and other petroleum oils with automated test sequencing and atmospheric pressure correction. The unit integrates an ARM microprocessor, color LCD and resistive touchscreen for operator interaction.
Key features
Automatic ignition and automatic lock, display and print of results
Automatic cooling after test completion (forced air cooling)
Automatic atmospheric pressure correction
Externally adjustable igniter brightness
Heating profile conforms to ASTM D93 and GB/T 261-2008
Accurate measurement with good repeatability and stable performance
Integrated thermal printer and storage for up to 1000 results
Applications
Laboratories, power utilities, transformer manufacturing and maintenance, petroleum and chemical industries, quality inspection and scientific research
Operation and measurement
The instrument follows the standard heating curve (ASTM D93, GB/T 261-2008), triggers automatic ignition as temperature approaches the flash point, then locks, displays and prints the result while initiating automatic cooling.

Operation precautions
1. During the testing process, users should be careful to avoid burning their hands;
2. After testing a sample, wait for the instrument to cool down for 20 minutes before starting a new testing process;
3. The instrument should be placed in a location with low air flow (such as a fume hood) to prevent external airflow from dispersing smoke and interfering with test results;
4. When replacing the test sample, the oil cup needs to be rinsed with the sample;
5. When the instrument malfunctions, the power should be cut off immediately. After the instrument cools down, professional personnel should be hired for maintenance and troubleshooting before continuing to use it to avoid accidents
Maintenance and Care
1. The instrument should be used in a non corrosive environment.
2. The instrument should be stored at 10-50 ℃ with a relative humidity below 85%;
3. If the instrument is not used for a long time, it should also be turned on regularly. Long term shutdown can accumulate dust and moisture, which may cause abnormal operation when restarted. It is recommended to turn it on at least once every two weeks for 2 hours each time
