A range of low-cost machines for testing a variety of foods - including fruit, pasties and cheese - has been launched by the UK-based Zwick Roell Group.
Called Basicline, the benchtop digital series is said to provide the best of Zwick performance and engineering quality in machines priced to compete with comparable makes.
Intended chiefly for testing and evaluating components, assemblies and materials, the machines can be equipped for the penetrative, cutting and compression testing used in checking the quality and freshness of foods.
Four BasicLine models are available, from 0.5kN to 20kN capacity, the smallest with a single-column load frame and the other three with twin-column frames. Guidance rods ensure precise and smooth positioning of the moving crosshead during testing.
Forces are measured by a purpose-designed load cell attached to the crosshead while tests are controlled and analysed by Zwick's advanced testXpert software, which can be linked to a PC if required.
The digital measurement system also provides automatic zero-point setting and automatic detection of the load cell and of the setting and calibration parameters. Additionally a range of accessories and tooling is available which enables the machines to perform a wide variety of tests. They include wedge, screw and pincer grips, a compression test kit and a three-point flexure test kit.
