A versatile and easy-to-use materials tester, the single-column OmniTest is available in 5 kN and 7.5 kN capacities. Controlled by VectorPro MT, Mecmesin's newly developed materials testing software is designed for use in QC and R&D laboratories.
Higher capacities of 10 kN, 25 kN and 50 kN are available in the OmniTest twin-column range.
OmniTest test frame
A single-column motorized test frame designed to apply tensile, shear, flexural and compressive forces from 2 N right up to a capacity of 7.5 kN (1686 lbf).
Its versatile construction makes it perfectly suited for testing all kinds of materials in quality control or R&D environment.
Overview
To suit your materials testing requirements the OmniTest range is available as two models of a1 single-column materials tester (5 kN or 7.5 kN) and as 3 models of a dual-column tester (10 kN, 25 kN and 50 kN).
Designed for versatility and ease of use the OmniTest will appeal to users, whatever their skill or experience. They all fit comfortably on your bench-top, making them ideal for use in QC and R&D laboratories.
All OmniTest models are controlled by VectorPro MT software running on a PC. OmniTest delivers consistency and reliability by controlling the key test parameters of stress/strain, force/displacement and speed/load rate.
Whether you need to know the Young's Modulus, Offset Yield, Ultimate Tensile Strength or a whole host of other materials characteristics, the OmniTest has you covered.
The single-column OmniTest materials testing system comprises five key elements:
Test frame
The single-column OmniTest materials testers feature a precision ballscrew with a linear slide mechanism that drives a solid crosshead with an ELS loadcell. Excellent rigidity and strength with intuitive controls make the tester easy to use even for novice operators.
The construction of these single-column materials testers provides the crosshead travel required for conducting elongation tests up to 650mm, while also delivering the strength capability for mid-load break tests on rigid materials. All models are ideal for general-purpose testing of specimens to determine their tension, compression, flexure, shear and fracture characteristics.
Protective bellows prevent dust and splintered materials from becoming trapped inside the machine. Upper and lower safety limit switches minimize the risk of accidental damage caused by grips colliding.
For operator safety, a range of protective shields and enclosures is available, for situations where specimens may shatter or create projectiles upon failure.
Designed to apply tensile and compressive forces from 2 N right up to a capacity of 7.5 kN their high-quality construction, manufactured under ISO 9001 quality standards, ensures the ultimate in repeatable materials testing.
When seeking to precisely measure forces across a wide range it is often necessary to use multiple loadcells. The dovetailed crosshead design of the OmniTest minimizes operator setup and configuration, by quickly and easily sliding on a new loadcell that is automatically recognized by the software.
The base plate of the OmniTest is pre-drilled with threaded holes to connect a wide range of grips and fixtures. The OmniTest also uses quick-change (QC) adaptors that speed up the interchange of grips, for example when you need to perform a variety of different tests on different geometries of material.
Control the testing system using your own PC with VectorPro MT software and take advantage of its versatility to make it your ideal choice for materials testing.
Loadcells
The ELS range of high-resolution, precision loadcells is specially adapted to the OmniTest. They are fully interchangeable and plugged into the frame, where their calibration characteristics are immediately recognized by the tester without any input from the operator.
Fourteen different sensors, all measuring from zero, are available to cover the range from 2 N up to 7.5 kN. This ensures that you have the optimum selection to meet all your tension and compression testing needs. Measurement accuracy is an outstanding ±0.5% of displayed reading.
Each ELS sensor is delivered as a standard with its own calibration certificate traceable to national standards.
Software
VectorPro MT materials testing software is at the heart of the OmniTest materials testers.
VectorPro MT delivers outstanding control of the motor, whilst simultaneously collecting data at 500 Hz from the ELS loadcell and displacement encoder of the frame.
The software is intuitive for both operators and managers. Personalized user accounts and a streamlined design mean that the workflow is simple and creating step-by-step test methods according to the precise requirements of your testing procedures is easy.
Access to the most commonly used test methods enables operators to move seamlessly from task to task, and keep training time to a minimum.
By plotting stress/strain data in real-time on a graph the operator can immediately identify exactly how the test material is performing. Preset materials testing calculations are used to analyze the data to determine whether the specimen has met the pass/fail criteria.
Use the power of VectorPro MT to calculate Young's Modulus, Offset Yield, Ultimate Tensile Strength, Nominal Strain and a whole host of other materials characteristics.
At the end of the test, the comprehensive reporting module within VectorPro MT enables the operator to issue a test report as a PDF. Reports can be easily tailored to your customer's exact requirements and automatically emailed to them. Test data can also be exported to Excel or to the network for further analysis.
VectorPro MT generates a clear audit trail with electronic-signature functionality - a must for medical and pharmaceutical clients seeking compliance with FDA 21 CFR Part 11.
Extension measurement
When testing the extension or compressive deformation of a specimen it is often acceptable to measure the movement of the load cell and grips, as defined by the crosshead distance traveled (known as 'Grip Separation').
This is taken directly from encoders situated on the ballscrews of the OmniTest. VectorPro MT software compensates for movement encountered within the loadcell and grip string (known also as 'Correction for Machine Compliance') but it cannot be as accurate as measuring extension directly upon the specimen.
For materials requiring extension measurement to be taken directly on the specimen, a range of contact extensometers is available for use with the OmniTest.
The range of contact extensometers includes short-travel extensometers suitable for rigid materials (eg hard plastics and metals) through to long-travel extensometers designed for highly elastic materials (eg rubbers or soft plastics), simply select the model which best suits your material characteristics.
