Texture Analyzer - TVT 6700

Evaluation of texture is often based on sensory evaluation and experience. The TVT 6700 texture analyzer is rapid, objective and more sensitive and reproducible than subjective sensory judgement.

The TVT 6700 applies controlled conditions of stress or strain to food and other samples to measure a complete texture profile. It accurately measures compressive and tensile force and position over time using standard test modes including single and multiple cycle compression, tensile strength, compress-and-hold, extend-and-hold, fracturability and springback to describe product texture. Data is captured as a graph and stored in a tabular data base for analysis and export to spreadsheet programs.

The TVT 6700 texture analyser is user-friendly, efficient and versatile, with rigs and probes to quantify textural properties of a range of food products and materials.
