Automatic Volume Change ApparatusThe Automatic Volume Change Apparatus is used for measuring the volume change of a soil sample by monitoring the flow of water through the chamber of the unit. The lower assembly contains changeover valves, which when used in conjunction with the upper assembly provides limitless capacity. The unit can be used with a linear strain transducer, digital indicator, or as part of an automated system. It is accurate to better than ±0.05 ml and is easily de-aired in seconds. Includes connectors, valves, and tubing. Order indicator separately. Shipping wt. 21 lbs. ( 9.5kg) Automatic Volume Change Apparatus Manual Automatic Volume Change Apparatus– HM-2315 |

Pressure ControllerStand alone unit for accurate control of air pressure in the Triaxial laboratory testing. It provides automatic incremental back pressure saturation with B-value calculation and check, when used with HMTS (Humboldt Material Testing Software) and Humboldt Triaxial testing equipment. The on board digitalized and bias pressure regulators plus two air/water bladder systems (HM-4151A) and the distribution panel (HM-4152A) allow simultaneous control of the confining and back pressure while maintaining a constant differential pressure.

Digital Pore Pressure SetFor accurately measuring and monitoring pore water pressures and back pressure. For determining level of saturation (“B” parameter) during saturation stages of triaxial/permeability tests. Includes readout, pore pressure transducer, and de-airing block assembly.

De-Airing Water TankFor use with Triaxial/Permeability Distribution Panels. Cast acrylic chamber, 6" dia x 16"H (152 x 406mm). Head plate mounted with three fittings. One is modified to allow 1/4" tubing to pass through to tank bottom, one for filling with tap water and the other for extracting the water once de-aired. The third fitting is used to connect vacuum/pressure to tank. Shipping wt. 13 lb. (5.8kg) De-Airing Water Tank– HM-4187E |

Nold De-Aerator Water SystemCompletely self-contained unit produces 8-liter batches of de-aired water without the use of heat. Combined mechanical agitation and vacuum evacuation removes gasses at much higher rate than conventional heat-boiling methods. Will de-air water to less than 0.5 pph dissolved oxygen in 4 minutes. 1/55hp motor 110V, 60Hz. 7.5 x 7.5 x 20" (190 x 190 x 508mm). Shipping wt. 19 lb (8.6kg) Nold De-Aerator Water System– HM-4187 |
