Oil viscometer HZ1151

laboratoryfully-automaticlow-temperature

Product overview
The HZ1151 fully automatic apparent viscometer (CCS) by Huazheng is designed to measure the low-temperature apparent/dynamic viscosity of engine oils in compliance with GB/T6538-2010 and ASTM D5293. It performs measurements from -35 °C to -5 °C with 5 °C steps and integrates automatic temperature control and a color touch screen for test setup and result review.

Application and measurement range
Suitable for CCS (cold-cranking simulator) tests of engine oils. Typical measurement capability covers apparent viscosities from about 500 to 20,000 mPa·s and shear rates on the order of 10^5 to 10^4 s^-1 in the low-temperature range (examples reported at -5 °C to -30 °C depending on test configuration). The instrument is intended for laboratory and R&D use in lubricant testing.

Instrument features

• Microcomputer control with color touch-screen HMI; automatic calculation, display and print of results.
• Imported Omron temperature controller and cascade compressor refrigeration for high cooling capacity.
• Automatic speed detection and fine adjustment to control current and reduce manual error.
• Imported high-precision drive motor; test data storage and print capability.
• Automatic result calculation after calibration with standard oil; embedded OS for stable operation.
• Automatic shutdown and controlled temperature increase at test end to facilitate cleaning.
• Programmable temperature profiles: system follows user-defined non-linear temperature curves to reach setpoints.
• Built-in calibration function to calibrate system components and determine viscosity vs. motor speed relationship.
