Frequently Asked Questions

What is a gasoline octane rating tester?

A gasoline octane rating tester measures the anti-knock quality of gasoline using a standardized test engine. It determines the Research Octane Number (RON) and Motor Octane Number (MON) in compliance with ASTM D2699 and D2700.

What is a diesel cetane number tester?

A diesel cetane number tester evaluates the ignition quality of diesel fuel by measuring the ignition delay in a standardized engine. It complies with ASTM D613 and is essential for fuel quality control in refineries.

What is a high-frequency reciprocating machine for diesel lubricity?

This machine evaluates the lubricating ability of diesel fuel by simulating metal-to-metal contact under high frequency. It measures the wear scar on a ball per ASTM D6079 to ensure fuel protects engine components.

Do you provide GOST-compliant models?

Yes, we can provide GOST-compliant versions of our octane and cetane testers upon request. Our instruments are adaptable to various international standards.

Can your instruments replace imported brands?

Absolutely. Our products are designed to match or exceed the functional performance, accuracy, and stability of leading imported instruments, offering a cost-effective alternative with local support.
