General Info

With its repeatability of ±0.0001 inch, the laser-based LOTIS® QC-20 has set a new standard in hose measurement precision.

The QC-20 is the fastest and most accurate non-contact measurement system available for hose inspection. Operator error is virtually eliminated due to the QC-20’s precise, simultaneous measurements, which gages dimensions with no product distortion.

  • Measure straight, oval, and curved hoses
  • No product distortion
  • Captures 4 simultaneous measurements:
    • Hose ID
    • Hose OD
    • Wall Thickness
    • Wall Variation
  • Measurement cycle of 4 seconds
  • Track sample deviations in real-time
  • Meet exact product tolerances for customers
  • Reduce costs from waste, returns and warranty issues

Fast measurement = Higher throughput!

1600 equally spaced data points are captured with every data set. The QC-20 produces more data than any other system available – and does it faster. The operator simply places the hose section on the end and presses a button to record measurements, which takes only 4 seconds. The result is higher throughput rates and significant savings – realized through reduced labor costs, material waste and fewer returns and warranty issues.

Imagine a GR&R of less than 10.7% – you can have it
