Stable Micro Systems' MT-LQplus Technical Specifications

The SMS MT-LQPlus Texture Analyzer is designed and manufactured for long-term reliability and accuracy of materials testingand leather testing applications. It will perform tests in both tension and compression for cycling, flexure, constant strain and stress relaxation . There are many built in test procedures to meet most requirements and standards.

The MT-LQPlus is relatively light and compact so it can be carried if required.

The MT-LQPlus can have a 1Kg, 5Kg, 25Kg, 50Kg, 100Kg, 250Kg, 500Kg or 750Kg load cell fitted and changing load cells takes less than a few minutes.

Operational reliability is enhanced by the inclusion of total mechanical overload protection and electronic monitoring so that the instrument can safely recover even from full-speed impact. User setable position limit stops are also provided. Additional pre-programmed test procedures include Texture Profile Analysis, Adhesiveness and Sine oscillation.

Among the applications for the MT-LQ are:

LASTOMETER
This is also known as the 'Ball Burst Test' and identifies the strength and distension of the grain. The MT-LQplus exceeds the requirements of the Standard as the test is made without stopping the test to measure grain crack. It is now accepted that some material relaxation must occur when the test is stopped, therefore the grain crack load is very accurately captured. 'Material Yield' at grain crack is also accurately identified.

Results:
1) Strength and distension of the grain at grain crack.
2) Measurement of Yield at grain crack.
3) Strength and distension of the grain at ball burst.
4) Distance between grain crack and ball burst.

ADHESIVE PEEL TEST
The measurement of peel strength of adhesive joints where one or both substrates are flexible.

Results:
1) Initial peak peel force.
2) Mean peel force.
3) Maximum peel force.
4) Minimum peel force.
5) Work done.
6) Automatic identification of the 10 maximum and 10 minimum peak and calculation of the average of the maximum and minimum peak forces.
7) Automatic conversion of all peel forces into peel strength.

SLOT AND TONGUE TEAR TESTS
The measurement of tear strength.

Results:
1) Maximum tear force
2) Average tear force
3) Minimum tear force
4) Work done
5) Automatic identification of the 10 maximum and 10 minimum peak forces. Calculation of the average of the maximum and minimum peak forces.

TENSILE TEST
Results:
1) Tensile strength.
2) Elongation at specific load.
3) Elongation at break.
4) Modulus.
5) Load and elongation at grain crack.

SOFTNESS
The loop test as means of quantifying leather softness has been published by the BLC - The Leather Technology Centre.
A loop of leather is compressed by a defined distance and then decompressed. The energy used in compressing and the energy returned by the sample during decompression is measured.

Results:
1) Compression and decompression energy
2) Peak force
3) Springiness

BAGGINESS
The objective of the test is to measure the residual deformation of the test sample after cyclic bi-axial strain.

The material is cycled, using the Lastometer, a defined number of times to a specific force or distance and at each cycle the distance is held for a set time whilst the material relaxes At the end of the set number of cycles the material is allowed to relax after which the is residual deformation automatically measured.
