1. What Is a Rotational Viscometer?
A Rotational Viscometer is used to measure rheological properties of oil well cement slurry, including viscosity, gel strength, shear stress, and flow behavior under different rotational speeds.
The instrument is widely used for:
- Cement slurry rheology testing
- Gel strength testing
- Cement additive evaluation
- Slurry formulation optimization
- Oilwell cement laboratory quality control
The NXNJ0020 can automatically conduct viscosity testing and gel strength testing according to API standards while automatically recording test data.
2. Key Features of NXNJ0020 Rotational Viscometer
Automatic, Manual and Gel Strength Test Modes
Users can flexibly switch between automatic mode, manual mode, and gel strength test mode according to different laboratory testing requirements.
Automatic API Standard Testing
In automatic mode, the instrument measures viscosity according to API standards, automatically changes rotational speeds, calculates average readings, and records test data automatically.
Automatic Gel Strength Test Function
Users only need to tap the "GEL" button on the touch screen, and the instrument will automatically complete the gel strength test and record test data.
Touch Screen Interface
The touch screen interface allows users to conveniently view test data, switch test modes, and operate the instrument more efficiently.
USB and Ethernet Communication Functions
The USB port supports screenshot saving of test results for statistics, while the Ethernet port allows connection with computer software for data recording and remote upgrades.
Automatic Data Recording and Display
The instrument automatically records and displays test data on the touch screen during testing, reducing manual operation and improving test efficiency.
Smart Calibration System
The smart calibration system reduces the need for frequent spring adjustment as long as the spring remains linear, improving calibration reliability and reducing maintenance requirements.
Regression Analysis and Two Point Method
After testing, the instrument can automatically calculate rheological data using regression analysis or the two point method, saving time and simplifying data analysis.
Multiple Rotation Speed Options
The instrument supports 12 rotational speeds and allows flexible switching according to test requirements.
