MultiTest-dV | PPT Group

The MultiTest-dV is a superior motorised tensile and compression tester offering outstanding value. Designed for precision-controlled compression and tension testing the MultiTest-dV delivers easy to use controls, backed by sophisticated electronics, make it the ideal choice for a wide range of routine testing.

It improves greatly on the variability encountered with manual testers where tension and compression are applied by hand at varying speeds. By applying force at a constant speed, whilst gripping the sample in a uniform manner, the motorised MultiTest-dV significantly enhances the repeatability of test results.

Operators can perform routine batch testing with excellent throughput, minimising testing time, and benefit from the convenience associated with our motorised tensile testers.

The MultiTest-dV is available in two different configurations:

Simple tensile measurement

Test to a target displacement limit or, when using any one of the Mecmesin range of Advanced Force Gauges (AFG), to a load limit or break.

Add VectorPro Lite software to a MultiTest-dV with AFG, for data acquisition, plotting of graphs, calculation of results, plus reporting and exporting of test data.

Sophisticated materials tensile measurement

Fit a dedicated ELS loadcell and connect up to VectorPro MT software to use your MultiTest-dV as an entry-level materials tester.

Control your whole test sequence with simple, step-by-step programmes. Perform both standard calculations like peak, load at displacement and more complex calculations such as Youngs Modulus, and offset yield strength.

Test frame

The MultiTest-dv is a versatile single-column, motorised tester designed for ease-of-use by operators of all levels. There are 3 models in the range with ratings of 0.5 kN, 1 kN and 2.5 kN and offering a crosshead travel up to 1186 mm (46.7").

Each occupies minimal bench space and are ideal for applying tensile and compressive forces in a variety of applications.

It delivers superior performance via its control panel and multifunctional control wheel, which allows the precise selection of test parameters such as speed and target force/displacement. Coloured LEDs clearly indicate the machine status during testing and operators can effortlessly follow the progress of the test from the force & displacement panel.

For more in-depth recording and analysis of test data, the MultiTest-dV can be connected via its USB output port to VectorPro Lite advanced data-acquisition and plotting software package.

Adjustable safety limit switches are fitted to ensure that specimens cannot be stretched too far or grips crushed together.

The MultiTest-dV is fitted with a dovetailed crosshead for quick and easy interchange of force gauges or loadcells. Grips and fixtures can be rapidly fitted to the anvil plate which is pre-drilled with threaded holes for easy connection.

With no model weighing more than 31 kg (68 lbs), its compact design and small footprint make it an ideal bench-top tester for use in the quality-control laboratory or production area.

Force Gauge

Our Digital Force Gauges are self-contained devices comprising an internal loadcell and its own display. We recommend our VFG Touchscreen or AFG Advanced Force Gauges for use with the MultiTest-dV.

There are 10 models ranging in capacity from 2.5 to 2500 N (0.5 - 500 lbf) each featuring an impressive measurement accuracy of ±0.1% of full-scale.

The gauge is positioned on the crosshead of the test frame via a dovetailed fixing and continuously measures & displays tension/compression, whilst simultaneously capturing the maximum peak readings in the background.

When the gauge is connected to the MultiTest-dV via an interface cable it can transfer the displayed 'live' load reading to the front panel and perform basic control of the test. This is achieved by configuring settings within the AFG to send a signal to the test frame to 'stop' or 'stop and reverse' when a load limit or specimen break is detected.

Tension and compression values obtained by the gauge can be transmitted directly to a PC or printer for the recording of results.

Alternatively, force readings are combined with displacement readings within the MultiTest-dV and sent to the USB output port to create a data-package, which is accessed by VectorPro Lite software for plotting graphs, calculation of results and creation of test reports.

Loadcells

The Enhanced Load Sensor (ELS) is positioned on the crosshead of the test frame and communicates with the MultiTest-dV for precision testing of materials when combined with VectorPro MT software.

Ranging in capacity from 2.5 to 2500 N (0.5 to 500 lbf) the ELS loadcells are fully interchangeable, their individual calibration characteristics are immediately recognised by the MultiTest-dV. This ensures that you have the optimum selection to meet all your materials testing needs without the need for lengthy set-up.

Measurement accuracy is an outstanding ±0.5% of reading.

Gripping fixtures

Holding your test specimen in place without it slipping is essential to obtaining repeatable results. Mecmesin have an extensive range of grips and fixtures to hold a variety of components and materials. They include wedge grips and vice grips for tensile testing, compression plates and bend jigs, friction tables plus many more.
