The HPHT Consistometer is a high-performance laboratory testing instrument designed for high temperature and high pressure evaluation of oil well cement systems. Developed for demanding cement testing applications, the NZCJ HTHP Consistometer provides an integrated solution for monitoring cement consistency, temperature and pressure under simulated downhole conditions. With a large touchscreen interface, automatic pressure regulation, smart calibration technology and reliable PLC control, the system helps oilfield laboratories, cementing service companies and research institutions improve testing efficiency, operational convenience and measurement reliability.
The NZCJ series is available in both single-cell and dual-cell HPHT consistometer configurations, allowing users to select the appropriate system according to laboratory workload and testing requirements. The standard single-cell model is NZCJ2125R, while NZCJ2225R provides a dual-cell configuration for higher testing capacity. The dual-cell design can be particularly useful for laboratories that need to increase testing throughput while maintaining controlled high-temperature and high-pressure test conditions.
Designed for oil well cement testing, the NZCJ HTHP Consistometer enables users to directly enter test parameters through the large touchscreen. Test parameters, instrument status, temperature, pressure and consistency curves can be viewed clearly on the display, simplifying daily operation compared with conventional instruments that require users to monitor multiple independent dials. After the required test parameters are configured, the instrument can perform automatic operation with one-button control.
Automatic pressure regulation is another important feature of this high temperature high pressure cement testing equipment. During testing, the system can regulate pressure automatically according to the required test procedure, helping simulate high-temperature and high-pressure downhole conditions while reducing errors associated with manual pressure adjustment. Users can also establish alarm limits for multiple parameters, including consistency, pressure and air supply pressure, allowing abnormal operating conditions to be identified more efficiently.
Accurate consistency measurement is essential when evaluating oil well cement behavior. The NZCJ HTHP Consistometer incorporates an optimized potentiometer designed to improve measurement contact and simplify calibration to 0 Bc. The spring is positioned at the bottom of the potentiometer, helping reduce the influence of cement slurry accumulation and making routine calibration and cleaning more convenient.
The system also incorporates a smart calibration concept that reduces the need for frequent spring adjustment when consistency measurement accuracy is maintained through appropriate zero-point correction. This design can help laboratories reduce maintenance requirements and improve operational efficiency during repeated oil well cement consistency testing.
The NZCJ HTHP Consistometer is designed with a built-in cast-aluminum chiller incorporating a stainless-steel coil pipe. The cooling structure increases heat transfer efficiency and helps shorten the cool-down period after testing. The oil reservoir is also equipped with a cooling function to improve testing frequency and laboratory productivity.
For applications requiring testing below ambient temperature, the instrument can be connected to an external chiller. This provides additional flexibility for laboratories working with different cement formulations and temperature test requirements. The temperature controller can be configured directly through the touchscreen, providing a more straightforward operating experience.
The NZCJ HTHP Consistometer combines automated control, touchscreen operation and durable mechanical construction into a professional HPHT cement testing system. The stainless-steel exterior improves durability, while the PLC control platform provides a reliable foundation for future functional upgrades through programming.
The available models provide a maximum temperature of 315°C and a maximum working pressure of 275 MPa, with adjustable rotation speeds from 0–300 rpm, depending on the selected configuration. The consistency measurement range is 0–100 Bc. These specifications make the NZCJ series suitable for demanding laboratory environments where accurate control of temperature, pressure and cement consistency is required.
Testing data presented in the product documentation demonstrates consistency between NITHONS instrument results and the relevant theoretical values. The document also states that the test data are in conformance with API 10A and GB/T 10238, satisfying API certification requirements for oil well cement.
For laboratories with standard testing workloads, the NZCJ2125R single-cell HTHP Consistometer provides a practical configuration for routine oil well cement testing. For laboratories requiring increased testing capacity, the NZCJ2225R dual-cell HTHP Consistometer offers a higher-capacity configuration.
The dual-cell model is especially suitable for cement laboratories, oilfield service companies, cement manufacturers and research organizations that perform frequent high-temperature and high-pressure cement tests. Selecting a single-cell or dual-cell system allows customers to match equipment capacity with their laboratory workflow and future testing requirements.
The NZCJ HTHP Consistometer can be used for laboratory evaluation of oil well cement under simulated high-temperature and high-pressure conditions. Typical applications include oil well cement consistency testing, cement thickening behavior evaluation, HPHT cement laboratory testing, cement formulation research and quality control.
For oilfield laboratories and cementing service companies, reliable laboratory data can support cement slurry formulation, quality evaluation and technical research before field operations. By combining automated pressure control, real-time test data display, programmable control and flexible configuration options, the NZCJ series provides a comprehensive platform for professional HTHP oil well cement testing.
For laboratories looking for a reliable HTHP Consistometer, HPHT Consistometer, oil well cement testing equipment or high temperature high pressure cement testing system, the NZCJ series offers configurable single-cell and dual-cell solutions with advanced control and measurement functions.
Sino-Japanese joint venture Tianjin Nithons Technology Co., Ltd. was established in 2013, focusing on the research and development, manufacturing, sales and after-sales service of a new generation of oil cementing testing instruments and related accessories.
