Detailed introduction

The soil moisture characteristic curve, also commonly referred to as the soil characteristic curve or the soil pF curve, describes the relationship between soil water potential (soil water suction) and soil moisture content.

Main technical specifications

1. Soil moisture characteristic curves are typically determined using methods such as pressure membrane (chambers) and centrifuges. The centrifuge method is simpler and more time-efficient than other methods, enabling measurement over a wider range of suction pressures. It is widely used in dynamic simulations of soil moisture. This centrifuge is specifically designed to measure the pF (water potential) values corresponding to soil water content.

2. Microcomputer-controlled, driven by a high-torque variable-frequency AC motor, offering stable operation, low noise, and high speed accuracy.

3. It features a high-performance compressor unit from an imported brand and uses the fluorine-free refrigerant R404a, meeting environmental protection requirements and delivering excellent quality and performance.

4. The large-screen true-color TFT touch screen offers simple control and operation, provides intuitive display, and allows simultaneous on-screen display of both set parameters and real-time operating parameters.

5. Large-capacity data storage and fault record information facilitate the tracking of operational history data. Relevant data can be exported and printed.

6. A powerful control system enables segmented stepped centrifugation, pre-set program recall, and tiered password management, ensuring the instrument’s safe and reliable operation and facilitating precise management.

7. Equipped with an electronic door lock, it features multiple protection functions including door cover protection, overspeed protection, overtemperature protection, and imbalance protection, as well as an automatic fault alarm function, ensuring safety and reliability.

8. Features 10 programs for acceleration curves and 11 programs for deceleration curves, with customizable settings for both acceleration and deceleration times. This further ensures optimal centrifugation performance and prevents secondary settling of samples.

9. Uses an integral sealing ring made of food-grade silicone rubber, compliant with GMP certification. The centrifuge has obtained U.S. FDA certification.
