The tester provides graphical display, showing real-time parameters such as  current, speed, viscosity, and curves.

The tester features an integrated structure, performing detection and  cleaning entirely within the main unit, without requiring any external  devices.

FAQ

1. What is this product?

The Automatic Engine Oil Apparent Viscosity Tester (CCS) is a precision instrument based on the Cold Cranking Simulator principle. It measures the apparent dynamic viscosity of engine oils under low-temperature, high-shear conditions that simulate real engine cold starting, in compliance with GB/T 6538 and ASTM D5293.

2. What is this product used for?

It is used to evaluate the low-temperature cranking performance of engine oils and to verify SAE winter viscosity grades (such as 0W, 5W, 10W). It is widely applied in lubricant quality control, formulation development, and compliance testing.

3. Why is this product important?

CCS viscosity directly affects engine startability and initial lubrication at low temperatures. Accurate measurement ensures compliance with SAE J300 limits and helps prevent cold-start wear, starter overload, and poor oil circulation.

4. What industries is this product suitable for?

Suitable for lubricant manufacturers, petrochemical laboratories, automotive OEM labs, third-party testing organizations, and research institutes involved in engine oil evaluation.

5. What types of this product are available?

Common configurations include fully automatic CCS testers (integrated and one-button operation), semi-automatic models, and research-grade systems with extended temperature capability.
