Model A1190 Automatic Closed‑cup Flash Point Tester determines the closed‑cup flash point of petroleum products for samples tested in a sealed environment, such as transformer oil. It adopts a touch‑screen instead of keyboard operation, with a large‑screen LCD full‑Chinese man‑machine dialogue interface. Full‑screen touch‑key prompts guide input for convenient and fast operation. Equipped with open‑ended fuzzy control integrated software and modular structure, it complies with Chinese national, US and EU standards. It is widely used in railway, aviation, electric power, petroleum industries and scientific research institutions.

The instrument adopts the Pensky-Martens Closed Cup Method, which is widely used for testing:

• Diesel fuel
• Fuel oil
• Lubricating oil
• Transformer oil
• Petroleum products
• Solvents
• Other combustible liquids

The A1190 integrates automatic sample heating, stirring, ignition, flash detection and result calculation, reducing human operation errors and improving laboratory testing efficiency.

The instrument complies with major petroleum testing standards including:

GB/T 21615-2008

ASTM D93

GB/T 261-2008

What Is Flash Point Testing?

Flash point is the lowest temperature at which vapor generated from a liquid sample can ignite when exposed to an ignition source under controlled conditions.

Flash point testing is an important safety and quality parameter for petroleum products.

It helps determine:

• Fire hazard level
• Storage safety
• Transportation requirements
• Fuel quality
• Product compliance

Working Principle

The A1190 uses the Pensky-Martens Closed Cup Flash Point Method.

Testing process:

Step 1

The petroleum sample is placed into a closed test cup.

Step 2

The sample is heated at a controlled temperature increase rate.

Step 3

The instrument automatically introduces the ignition source at preset intervals.

Step 4

The detector identifies the moment when vapor flashes.

Step 5

The system records and displays the flash point temperature.

Compared with manual flash point testing, automatic operation improves repeatability and reduces operator influence.

Applications

Petroleum Refineries

Used for:

• Fuel quality inspection
• Production control
• Finished product testing

FAQ

Q1: What is an Automatic Closed Cup Flash Point Tester?

An Automatic Closed Cup Flash Point Tester is a laboratory instrument used to measure the flash point temperature of petroleum products and flammable liquids using a closed cup method.

Q2: Which standard does A1190 comply with?

The A1190 complies with ASTM D93 Pensky-Martens closed cup flash point testing requirements, as well as GB/T261-2008 and GB/T21615-2008 standards.

Q3: What samples can A1190 test?

It can test:

• Diesel fuel
• Lubricating oil
