Labmate Automatic Oil Acidity Tester measures acid value in petroleum products and lubricating oils across a 0.001–1.000 mg KOH/g range at 0.001 mg KOH/g resolution.

Potentiometric titration determines total acid number at 0.3% repeatability and deviation below 0.5%, supporting oil degradation and lubricant monitoring.

Manufactured for power plants, transformer service centers, and petrochemical laboratories performing acid number quantification and oil analysis. ASTM D974 compliant.
