Why Automated Measurement?

Turn Visual Evaluation Into Comparable Results

Visual Evaluation

Fast, but Operator-Dependent

Experienced operators can assess distortion quickly, but results are harder to compare consistently across people, shifts and production periods.

FZT-2 Measurement

Quantitative and Repeatable

FZT-2 provides a consistent measurement method with quantitative results and time-stamped records for comparison and review.

Reporting and Traceability

Every FZT-2 Measurement Becomes a Quality Record.

FZT-2 automatically generates a report after each test. Time-based file naming makes it easier to find results, compare production periods and investigate later quality questions.
