![FlexPanels - 1-Cell Control Panel](http://klpconstructionsupply.com/cdn/shop/products/HM-4150.3F_{width}x.png?v=1701975427)
Supports the following standards: ASTM D4767, ASTM D5084, ASTM D6035, ASTM D7181, BS 1377 PART 6 1990 The HM-4150 1-cell, 3-burette control panel provides pressure controls and readouts for permeability and triaxial applications. It can control all the functions of a single cell, however with the addition of Auxillary Panels it can control the operations of up to five (5) cells. Controls include: a digital, readout pressure meter, a pressure supply gauge, a master pressure regulator, a vacuum supply gauge, a master vacuum regulator, de-aired water tank controls, tap and de-aired water supply outlets and pressure and vacuum outlets. FlexPanels can manually measure volume change or permeability in a triaxial test sample without the use of a volume change apparatus, a distinct benefit when compared to air/water bladder systems.
