Product Introduction
The UHV-655 Automatic Open Cup Flash Point Tester is an automatic open‑cup flash point and ignition point tester designed for measuring open flash point and fire point of transformer oil and other petroleum products in laboratory and inspection environments.

Overview / Key functions

• Automatic open‑cup measurement of flash point and ignition point with integrated test sequence, automatic cooling and user prompts.
• Simultaneous detection of flash point and ignition point and built‑in printing of results.
• High‑precision temperature control (error controlled within ±1.5°C, resolution 0.1°C) and stable repeatability under specified standards.
• Built‑in clock and data retention to display date/time and preserve results after power loss.

Standards & repeatability

• Test method and repeatability comply with GB3536-2008 (equivalent to ASTM D92) and GB/T 267-88; repeated measurements on the same sample show differences ≤ 4°C under standard conditions.

Nickname / Alternate names

Notes of Automatic Open Cup Flash Point Tester

• (1) It is best to place the instrument in a ventilated kitchen during testing to prevent external airflow from affecting the test results.
• (2) The flash point sensor cannot be immersed in the sample, otherwise it will affect the measurement results.
• (3) Do not use force to pull the detection head or swipe the scanning rod.
• (4) Please note that the two circular rings of the flash point sensor should not come into contact, otherwise it may cause misoperation.
• (5) When repeating the sample, it should be ensured that the temperature of the furnace plate and sample is below 56 ℃. Excessive temperature can affect the measurement results.
• (6) Each time the sample is replaced, the open cup should be kept clean, and a good contact surface should be maintained between the outer bottom of the open cup and the heating furnace.
• (7) The sample should be placed in an open cup slightly below the scale line, as the volume of the sample increases with temperature. The amount of samples loaded each time should be kept as consistent as possible.

Scope of application of Open Cup Flash Point Tester

• The fully automatic open flash point tester is widely used in railway, aviation, power, petroleum and scientific research departments, providing scientific basis for the safety assessment of petroleum products, solvents and other flammable liquids. By accurately measuring the flash point and ignition point, relevant industries can reasonably formulate storage temperature, transportation conditions, and fire and explosion prevention measures to ensure production and operation safety.
