The Automatic Closed Cup Flash Point Tester is a dedicated instrument for precise flash point determination using the Pensky-Martens Closed Cup method.

Under controlled heating conditions, petroleum products release vapor that mixes with air inside a sealed cup. The lowest temperature at which this vapor ignites when exposed to an ignition source is defined as the flash point.

This model is specifically engineered for laboratories that require accurate and compliant closed cup flash point testing, without the complexity of dual-mode systems.

It is ideal for petroleum, chemical, power generation, and industrial quality control laboratories focused on ASTM D93 applications.

The Automatic Closed Cup Flash Point Tester is suitable for:

• Lubricating oils
• Fuel oils and diesel
• Hydraulic oils
• Transformer oils
• Chemical solvents requiring closed cup testing
• Chemical liquids

Widely used in:

• Oil refinieries
• Lubricant production plants
• Power utilities
• Quality inspection laboratories
• Research facilities

The instrument is optimized for Pensky-Martens closed cup methodology with an adaptive PID-controlled heating curve that strictly follows ASTM D93 and ISO 2719 requirements.

An internal barometric pressure sensor continuously measures ambient pressure and automatically compensates flash point results for improved accuracy.

Differential thermocouple detection ensures reliable flash recognition and minimizes false triggering or missed ignition events.

The entire closed cup test cycle—including stirring, ignition, detection, cooling, and result printing—is completed automatically.

With a power consumption below 550W and a compact footprint (450 × 280 × 290 mm), this model is ideal for laboratories requiring space-efficient flash point testing equipment.

Platinum alloy electric ignition eliminates the need for external gas supply, enhancing laboratory safety and simplifying installation.

The instrument features automatic fault detection and operational self-check functions to ensure reliable daily operation.

Stores up to 10,000 test records with optional 500GB expansion for long-term data archiving.

This Closed Cup Flash Point Tester complies with international and national standards including:

• GB 261, GB 21615, SH/T 0315
• ASTM D93 – Pensky-Martens Closed Cup Method
• ISO 2719
