HR21M Soil pF Curve Refrigerated High-Speed Centrifuge, pF 2.0-4.2 (CAT#: STEM-AL-4295-ZJF)

HR21M Soil pF Curve Refrigerated High-Speed Centrifuge is designed for soil-water retention and pF curve measurements. The dedicated rotor processes four 100 mL soil samples per run. The system covers a pF measurement range of 2.0 to 4.2, corresponding to 0.1 to 15 bar. Its maximum speed is 10,000 rpm and its maximum relative centrifugal force is 14,758 × g. The refrigeration system controls the chamber from -20 to 40 °C. Microprocessor control manages the variable-frequency drive, temperature, and timing. Sixteen stored programs support repeatable soil analysis methods. The floor-standing enclosure accommodates the dedicated soil dehydration rotor and containers. The instrument supports controlled soil pF analysis within the documented sample and pressure-equivalent range.
