Product Overview

The HM501 Automatic Closed Cup Flash Point Tester is an automated instrument designed to precisely determine the minimum temperature at which the vapor of petroleum products (transformer oil, diesel fuel, fuel oil) ignites when mixed with air and heated under specified conditions in the presence of a flame.

 

Application Areas:

1. Power Industry:

Insulating oils such as transformer oil and switchgear oil. Ensures the flash point of new and in-service oils meets specification requirements, preventing fires during storage or equipment overheating.

2. Petrochemicals and Refining:

Gasoline, kerosene, diesel fuel, fuel oil, lubricating oil, crude oil.

Serves as a critical safety metric for petroleum products at the point of shipment, also used for product grading and pricing.

3. Chemicals and Coatings:

Solvents, thinners, coatings, resins. Assesses the flammability of volatile products to ensure production, packaging, and transportation comply with safety regulations.

4. Aviation and Shipping:

Jet fuel, marine fuel oil. Ensures fuels maintain a high flash point under specific conditions, safeguarding aircraft and vessel fuel tanks.

5. Quality Control and Research: Various unidentified petroleum products and novel liquid materials. Used for third-party safety assessments or safety studies of new formulation products.

Maintenance & FAQs

 

Q: What is this instrument used for?

A: It is employed for the automatic measurement of the closed-cup flash point of petroleum products such as transformer oil and diesel fuel. The flash point serves as a critical indicator of a petroleum product's safety performance, denoting the minimum temperature at which its vapour will ignite upon contact with an ignition source.

Q: Why is measuring the "closed-cup" flash point important?

A: The "closed-cup" method simulates the conditions within sealed containers (such as fuel tanks or storage tanks). The resulting flash point value is more conservative and safer, serving as the standard method for assessing the hazard level during transportation and storage.

Q: Is the operation complex?

A: Not at all. Fully automated operation: Simply add the oil sample, press the start button, and the instrument will automatically complete the entire process of heating, ignition, detection, result recording, and cooling.

Q: What safety precautions should be observed during testing?

A:

Ventilation: Operate within a fume cupboard or well-ventilated area to expel flammable vapours.
Keep away from combustibles: Strictly prohibit the placement of flammable or explosive materials near the instrument.
Gas inspection: Ensure no leaks in the ignition gas supply line.

Q: How long does testing one sample take?

A: Duration depends on the target flash point temperature. Typically 10 to 20 minutes. Higher flash points require longer testing times.

Q: What constitutes a pass for the measured flash point value?

A: Core principle: The higher the flash point, the greater the safety.

  •   Acceptable standards vary by oil type and must adhere to product specifications or standards (e.g., GB, ASTM).
  •  Transformer oil: Typically requires > 135°C - 140°C.
  •   Diesel fuel: Typically requires > 55°C - 60°C.
