The HM-5070A Direct Shear machine is an economical choice for performing direct/residual shear tests utilizing the dead-weight method and analog measuring devices.

The microprocessor-based system features a stepper-motor drive system and a 7" touch-screen display that allows the operator to control and monitor all test functions.

Like all elite series machines, the HM-5070A is built around Humboldt's integral, 4-channel data logger with touch-screen control, which allows the HM-5070A to be used as a standalone device capable of full test control and data logging. It can also be controlled by a networked computer at any location with access to the network. The carriage accepts shear box squares up to 4.0" (100mm) internal dimension. Forward and reverse measurements permit residual shear testing as standard. A built-in safety feature prevents the overloading of the load measuring system.

The HM-5070A is supplied complete with a 2,000 lbf (10kN) capacity load cell; 1" (25.4mm) horizontal strain transducer, and a 0.4" (10.2mm) vertical strain transducer. Shear box assemblies and related accessories are not included and should be ordered separately.

Counter-balance device for ASTM D3080 compliance is included. Not available anywhere else. Also available as a retrofit kit. HM-2560A.1
