1. What Is the NZCQ2120R HTHP Consistometer Used For?

The NZCQ2120R HTHP Consistometer is used to test cement slurry thickening time and consistency under controlled temperature and pressure schedules. It helps cementing engineers evaluate slurry pumpability and determine whether a cement system can safely complete placement before reaching critical consistency levels.

This single cell HPHT consistometer is widely applied in:
- Oilfield cementing laboratory thickening time testing
- Cement slurry formulation design and optimization
- Cement additive evaluation (retarder, dispersant, fluid loss additive, gas migration additive, etc.)
- Quality control testing for cementing service companies
- Research and development for high temperature cement systems

2. Why Choose NZCQ2120R Flagship Single Cell HPHT Consistometer?

Large Touch Screen for Data Display and Curve Recording
The NZCQ2120R HPHT Consistometer adopts a large-size touch screen to display and record test data, including temperature, pressure, and thickening time curves. Operators can easily observe test progress and review curve graphs directly on the interface.

EUROTHERM Temperature Controller Parameter Setting via Touch Screen
Users can set and adjust EUROTHERM temperature controller parameters directly through the touch screen, avoiding complex manual operations. The concise user interface makes parameter input and modification faster and more accurate.

Stable PLC Control for Future Function Upgrades
The instrument is equipped with stable and reliable PLC control. It can meet special testing demands and allows future upgrades through programming, making this model a long-term solution for modern cement testing laboratories.

One-Button Automatic Operation
After setting the test parameters, the system can operate automatically with one-button operation. This reduces human errors and improves testing efficiency compared with conventional HPHT consistometers.

Automatic Pressure Regulation to Simulate Downhole Conditions
During testing, the instrument can regulate pressure automatically according to API requirements, ensuring accurate simulation of downhole high temperature and high pressure conditions. This improves test reliability and reduces deviations caused by manual pressure adjustment.

Optimized Potentiometer (Accurate, Durable, Easy Calibration)
The optimized potentiometer design improves accuracy and durability. It is easier to calibrate and clean, supporting stable consistency measurement performance. The system allows convenient calibration to 0Bc and helps reduce frequent mechanical adjustment compared with conventional designs.

Smart Calibration System
The smart calibration system reduces the need for frequent spring adjustment. Once the zero point is corrected, the instrument can maintain stable measurement performance, improving repeatability and saving time for lab technicians.

Oil Level Tracking and Real-Time Monitoring
The change of oil level in the oil reservoir can be tracked, and the progress of oil filling and oil return can be monitored in real time through the touch screen. An oil level indicator is also available for direct observation.

Oil Level Sensor Alarm Protection
The oil level sensor can automatically send warning signals when the oil reservoir has insufficient oil or when the oil reservoir is filled up. This prevents operator negligence and enhances safe operation.

Alarm Reasons Displayed Clearly on Screen
Unlike conventional HPHT consistometers that only provide alarm indicators, NZCQ2120R displays alarm reasons directly on the touch screen. This improves troubleshooting efficiency and reduces downtime.

Shorter Cool-Down Time with Built-In Cast-Aluminum Chiller
The built-in cast-aluminum chiller improves cooling efficiency by accelerating heat diffusion and enlarging the contact surface. This design can effectively shorten cool-down time and improve overall test turnaround speed.

External Chiller Connection for Sub-Ambient Temperature Testing
With connection to an external chiller, tests below ambient temperature can be conducted. This feature expands the testing range and supports special cement slurry evaluation requirements.

Stainless Steel Surface for Enhanced Durability
The surface of the instrument is made of stainless steel, improving durability, corrosion resistance, and long-term reliability in cementing laboratories.

Emergency Manual Valve Design for Safe Operation
Both electrically operated valves and manually operated valves are available for the cooling system, air exhaust system, and air-to-cylinder system. In emergency situations (such as power failure), operators can end the test using manually operated valves only.

- Consistency curve (Bc vs time)
- Temperature curve
- Pressure curve
- Test status and alarm information

Users can take screenshots and output/save these screenshots for laboratory reports and traceable documentation.

6. Oil Level Monitoring System for Safer HPHT Testing

Unlike conventional HPHT consistometers, the NZCQ2120R includes a complete oil level monitoring system. The oil level change in the oil reservoir can be tracked in real time, and the oil filling/oil return process can be monitored directly through the touch screen.

Key advantages include:

- Oil level sensor alarm when reservoir is filled up
- Oil level indicator for direct manual observation

This system significantly reduces the risk of abnormal test interruptions caused by overlooked oil level issues.

7. Improved Cooling Efficiency and Faster Turnaround

The built-in cast-aluminum chiller is designed with a stainless steel coil pipe, improving cooling efficiency and extending service life. The optimized cooling structure enlarges the heat exchange surface and accelerates heat diffusion, effectively shortening cool-down time compared with conventional chillers.

For special test conditions, the system can be connected to an external chiller to conduct sub-ambient temperature tests (below room temperature).
