Description

Fast testing, safe operation and low energy consumption

The Seta PM-93 is a fully automated Pensky-Martens closed cup flash point tester, pre-programmed with all major international Pensky-Martens methods including ASTM D93, ASTM D8175, IP 34 and ISO 2719.

Designed for both routine quality control and unknown sample analysis, it operates in expected flash or search mode for maximum flexibility.

A fully motorised lifting head, intuitive touchscreen interface and automated test sequence ensure consistent, repeatable results with minimal operator intervention.

Safety is enhanced through optical fire detection with automatic fire extinguisher, automatic cup lock detection and over-temperature protection, ensuring compliant operation in accordance with ISO 2719 Annex B.

Laboratory efficiency is improved through quick-release components and Seta ‘Turbo Cool’ technology, enabling rapid cleaning and fast turnaround between tests. An energy-saving standby mode reduces power consumption by up to 40% compared to alternative Pensky-Martens instruments, lowering operating costs and CO₂ emissions.

Support and Compliance

ASTM D93-25 requires verification using Certified Reference Materials. Seta offers a range of CRMs to support compliance and reliable performance.

For aviation fuel flash point testing, Seta’s Jet A-1 Proficiency Test Scheme supports performance monitoring and ISO 17025 accreditation.

Feature Information

Designed for operator safety:
Safety is critical in Pensky-Martens flash point testing. The PM-93 incorporates multiple layers of protection to ensure safe operation in demanding laboratory environments:

• Optical fire detection with automatic fire extinguisher activation and continuous monitoring of the inert gas supply
• Automatic cup lock detection to ensure the test cup is correctly located and secured before operation
• Independent emergency stop button, positioned for safe and rapid shutdown
• Additional safeguards including PRT checks, safety dip before test start, over-temperature cut-out, gas flame relight and gas shut-off

These features provide confidence when testing volatile or hazardous samples in busy laboratory environments.

Precision, accuracy and compliance:
The PM-93 minimises operator influence and ensures consistent, repeatable results through advanced automation and measurement control:

• Fully automated flash point determination
• High accuracy Class A Platinum Resistance Thermometer (IEC 60751) with external traceable calibration (UKAS ISO 17025)
• Unique alignment design ensures correct lid and cup positioning every time
• Integrated draft shield for stable and repeatable conditions
• Automatic barometric pressure correction
• Password-protected calibration mode for performance verification
• Built-in Statistical Quality Control (SQC) software in accordance with ASTM D6299

This ensures confidence in results while supporting laboratory accreditation requirements such as ISO 17025.

High throughput flash point testing
To maximise laboratory productivity, the PM-93 is designed for fast turnaround and minimal downtime:

• Seta Turbo Cool rapid cooling system for faster test cycles
• Fast warm-up combined with efficient cooling to minimise overall cycle time
• Quick-release stirrer, lid and shutter for easy cleaning between tests
• Customisable test profiles to eliminate repeated data entry

Together, these features allow fast testing without compromising accuracy or safety.

Intuitive touchscreen operation
The PM-93 is designed for ease of use, reducing training requirements and simplifying daily operation:

• Fully automated “Press and Go” test operation
• Motorised raising and lowering of the test head
• Large colour touchscreen with intuitive user interface
• Real-time display of test progress and graphical results
• Seta status button for instant visual indication of instrument state
• Flexible data handling with LIMS connectivity, USB export and QR code transfer

This allows operators to work efficiently while maintaining full visibility of the test process..

Energy efficiency and low cost of ownership
The PM-93 is the most energy-efficient instrument in its class, designed to reduce operating costs and environmental impact:

• Intelligent standby mode reduces power consumption during idle periods
• Up to 40% lower energy consumption compared with similar Pensky-Martens testers
• Potential reduction of up to 150 kg CO₂ emissions per year

This delivers long-term cost savings while supporting laboratory sustainability goals.
