The CCS Tester G-1402 Apparent Viscosity Measurement Instrument features an integrated design combining both measurement and refrigeration systems, a global first. The instrument is compact and lightweight, with excellent performance. It is a fully automatic instrument integrating rotational speed measurement, constant calculation, and viscosity testing.

All technical specifications are manufactured in accordance with GB/T 6538-2022 and ASTM D5293 standards. The instrument is suitable for measuring the apparent viscosity of engine oils under shear stress of approximately 50,000–100,000 Pa, shear rates of 10⁵–10⁴ s⁻¹, at temperatures from -5°C to -40°C, with a viscosity measurement range of 1,200–35,000 mPa·s.

The instrument uses imported components for key parts, a precision intelligent temperature controller for temperature regulation, and a color LCD microcontroller to control the experimental process.

Applicable Standards

GB/T 6538-2022

The instrument is suitable for measuring the apparent viscosity of engine oils at -5°C to -40°C, with shear stress of 50,000–100,000 Pa, shear rates of 10⁵–10⁴ s⁻¹, and viscosity range of 1,200–35,000 mPa·s.

Instrument Overview

The instrument is equipped with a PLC programmable controller that automatically performs detection, calculation, and control, requiring no manual intervention throughout the entire testing process. It comes with imported standard oil and features an imported motor to drive the hard-shaft rotor.
