H1400pf High-Speed Refrigerated Soil Pf Curve Centrifuge For Agricultural Science
H1400pf High-Speed Refrigerated Soil Pf Curve Centrifuge For Agricultural Science
The soil moisture characteristic curve is generally also called the soil characteristic curve or the soil pF curve, which expresses the relationship between soil water potential (soil water suction) and soil moisture content.
The soil moisture characteristic curve is usually measured using pressure membrane (chamber) and centrifuge methods. The centrifuge method is simpler and less time-saving than other methods. It can measure a wider suction range and is widely used in soil moisture dynamic simulation. This centrifuge is used to measure the pF (water potential) value corresponding to the soil moisture content.
1. Microcomputer control, high torque frequency conversion AC motor drive, stable operation, low noise and high speed accuracy.
2. It adopts imported high-performance compressor unit and non-fluorine refrigerant R404a, which meets environmental protection requirements and has good quality effects.
3. Touch panel, programmable operation, and host operating parameters can be set and automatically stored according to requirements.
4. Digital display, user-friendly interface, simple and convenient operation: using silicon rubber integral sealing ring.
5. Reading conversion and setting between rpm/RCF is convenient and quick.
6. Equipped with electronic door lock, with door cover protection, over-speed, over-temperature, imbalance and other protection functions, automatic fault alarm function, safe and reliable.
7. There are 9-program speed-up curve/10 program speed-down curve, and the speed-up/down time can be set as required.
8. Food grade silicone rubber integral sealing ring is adopted, which conforms to GMP certification. The centrifuge obtained the FDA certification.
