The HM-5250-500.3F is a fully-automated hydraulic pressure controller, which is highly accurate up to 0-500psi (3500kpa) in pressure and 250ml in volume. It is designed specifically for geotechnical laboratory triaxial testing (UU, CU and CD) and provides control and monitoring of cell pressure, back pressure, pore water measurement and volume change when used with our Elite-series load frames, such as the HM-5020.3F. The HM-5250-500.3F is configured; for standard pressures, 0-500psi (3500kpa). It provides two (2) analog input channels (24-bit) for measuring pressures and two (2) encoder inputs for measuring volumes. In stand-alone mode, this pressure controller provides a 7" (178mm) touch-screen controller. This waterproof, touch screen provides colorful, at-a-glance monitoring of testing functions without the use of a computer. Operator can see all the data in several formats at the controller while the test is running. The test data can be viewed simultaneously or downloaded later to a computer in the lab, in the next room or at a different location, while also providing report generation capabilities from within Humboldt’s NEXT software or our enhanced test-specific modules.
