QM-FIT ｜ Enhancing Quality Inspection with a Faster and More Accurate Automatic Measuring System

🔹 Key Takeaways
- Automatic camera system detects and measures instantly when a workpiece is placed
- Fast measurement without setup or alignment
- 20-megapixel color CMOS camera with telecentric lens
- Automatic Pass/Fail judgment and measurement record
- Complies with Japan’s traceability standards (JCSS, NMIJ/AIST)

🔹 Mitutoyo QM-FIT: Superior Measurement Performance
In today’s manufacturing, speed, accuracy, and flexibility are vital.
The Mitutoyo QM-FIT vision measuring system answers these needs with the concept of “Place and Measure Instantly.”
It minimizes setup time and simplifies operation—ideal for small or thin precision parts.

🔹 New Concept — Place and Measure Instantly
Traditional measurement requires complex setup and alignment.
With QM-FIT, simply place the workpiece on the stage; the system automatically detects and measures it immediately.
This reduces preparation time and accelerates in-line quality inspection.

🔹 High-Resolution Optics for Micron Accuracy
A 20 MP color CMOS camera and telecentric lens deliver sharp, distortion-free images with ±10 µm accuracy.
The 15.6-inch touchscreen allows intuitive point selection using the Marker- function.

🔹 Automatic Detection, Easy for Everyone
QM-FIT recognizes circles, lines, and edges automatically.
Users just select the area on screen; results appear instantly with Pass/Fail display and guided instructions.
Even non-specialists can measure accurately and consistently.

🔹 Compact, Yet Laboratory-Level Precision
At only 366×407×621 mm, QM-FIT fits easily in production lines.
It supports JCSS/NMIJ-AIST traceability, ensuring reliable calibration and measurement confidence.

🔹 Before vs. After
- Before: Manual setup and alignment needed
➡️ After: Place the workpiece — auto measurement starts
- Before: Manual point selection
➡️ After: Detects multiple features automatically
- Before: Skilled operators required
➡️ After: Easy touchscreen control for all users

🔹 Applications
Ideal for small or thin workpieces needing high resolution—such as PCBs, connectors, and micro molds.
Simply place and measure—no setup or predefined points required.

🔹 Reliability
According to Mitutoyo (Thailand), QM-FIT combines ease of use with high accuracy for on-site applications.
It meets JCSS and NMIJ/AIST standards, ensuring repeatable, traceable measurements. [1][2]

🔹 Summary
Mitutoyo QM-FIT unites speed, simplicity, and precision in one automated vision system.
It improves quality inspection efficiency and sets a new benchmark for precision measurement in modern manufacturing.
