Core high speed refrigerating centrifuge, used to determine capillary pressure and wettability of core samples and related core properties.

Soil pF curve detection is determined by the relationship among soil suction, bulk density and weight water content, so as to obtain high-precision soil moisture characteristic curve pF.

Soil water characteristic curve is usually measured by pressure membrane (chamber) and centrifuge. Compared with other methods, centrifuge method is simple and time-saving, and can measure a wide range of suction. It is widely used in soil moisture dynamic simulation, meteorology, climatology, soil geography, hydrology, agricultural science and technology.

Characteristics of centrifuge were detected by soil pF curve:

1. Large torque AC frequency conversion motor, without toner pollution and extended service life.

2. Frequency frequency drive system and intelligent control system to ensure stable and reliable work.

3. The refrigeration system adopts the French Taikang compressor set, with arbitrary temperature adjustable, high temperature control accuracy and small noise.

4. Ultra-temperature, overspeed, electronic door lock, imbalance and other protection.

5. Soil with pF curve high-speed frozen centrifuge HR21M, the fuselage is full metal structure, stainless steel internal cavity, strong and durable.

6. Intelligent interface, TFT real color 4.3-inch screen, touch button dual control system, microcomputer control, synchronous display of set parameters and operation parameters.

7. Users can set 16 running programs and modify the control parameters of the running rotor at any time.

8. Programmable operation, 10 gear lift time for the user to set arbitrarily.

9. Soil centrifuge can show the speed rise, drop curve, centrifugal integral curve and temperature curve.

Expedited shipment

The changing of the shipping methods may have occurred when we are noticed from customer for the needing of rush order or lower rate of shipment delay. The related request is acceptable whenever in prior of the order is dispatched and heading to the designated shipping address.

Note: (PO) boxes or FPO/APO military addresses can only be shipped out by standard shipping method).

The shipping fare for the expedited shipment method may higher than the standard one you chose for, then please be aware that you may ask to pay for the balance for the pertinent shipment substitution.

Shipping cost all about

It is deeply appreciated to take your kind pardon for any misunderstanding about the shipping price due to the package is shipped from China.

The contract we have stipulated with FedEx, DHL, UPS and EMS is already set and therefore all merchandise is sent via Air rather than Ground. While this may not be the most cost effective for all customers, in terms of delivery time, ease of shipment and reliability we have determined that this is the most effective overall.

The shipping cost for all merchandises are displayed by adding items to your shipping bag, you can estimate shipping time and cost and acquire more shipping cost information from our site.

International Shipping

International shipping costs are calculated in U.S. currency based on estimated shipment weight and destination. Shipping costs for orders placed on the website are fairly accurate, but there are times when those estimates are incorrect. If we need to adjust shipping charges for your order we will contact you to authorize those additional shipping charges.
