High-Performance Automatic Viscosity Tester-Enviro Testers

Overview

High-Performance Automatic Viscosity Tester Method for Lubricating Oil. The instrument conforms to ASTM D7279-14 a test standard, the test process is fully automatic control, the fastest can be 30s out of the result. It is suitable for determining the kinematic viscosity of Newtonian liquids such as base oils, blended lubricants, biodiesel, biodiesel blends, residual fuel oils, marine oils and in-use lubricants.

Features

• Fully Automatic Operation – One-key start for measurement, cleaning, drying, result calculation, and data storage.
• Fast Measurement Speed – Measuring time as fast as 20 seconds, with an average test time of under 3 minutes.
• High Accuracy – Precisely controlled measurement conditions for reliable and consistent results.
• Dual Solvent Automatic Cleaning – Efficient cleaning with minimal solvent consumption (≤15ml per cycle).
• High-Precision Temperature Control – Uniform bath temperature with ±0.01ºC accuracy.
• Safety Features – Over-temperature protection and dry burning prevention.
• Quick Viscometer Replacement – Change viscometers without draining the bath liquid, within 2 minutes.
• Durable and Transparent Bath – Made of high-temperature resistant borosilicate glass for clear visibility and insulation.

Application

• Base Oil Analysis – Determines the kinematic viscosity of raw base oils used in lubricant formulations.
• Blended Lubricating Oil Testing – Ensures proper viscosity for optimal lubrication and performance.
• Biodiesel Quality Control – Evaluates viscosity to meet fuel standards and ensure engine compatibility.
• Biodiesel Blended Fuel Testing – Confirms consistency and efficiency in blended biofuels.
• Residual Fuel Oil Analysis – Assesses the viscosity of heavy fuel oils for industrial and marine applications.
• Marine Oil Viscosity Measurement – Verifies compliance with marine fuel regulations and engine requirements.
