The ProGage is API Metrology's portable 7-axis CMM arm, designed to move inspection out of the climate-controlled lab and onto the shop floor. At 536 grams the probe and handle assembly is among the lightest in its class — a deliberate choice to minimize operator influence on measurement data during long routines. The integrated controller eliminates the external cable pod found on earlier-generation arms, and dual hot-swappable batteries keep the system running cordlessly for over 10 hours without pausing to recharge.

What does the optional laser line probe add?

The ProGage accepts an HD or SD laser line probe that transforms the arm from a contact-only touch-trigger CMM into a hybrid scanning system. The HD probe delivers ±15 μm accuracy at up to 1,200,000 points per second with an effective scan width of 80–150 mm. This makes the arm capable of rapid surface digitization, freeform geometry inspection, and point-cloud-to-CAD comparison — tasks that would be impractical with discrete point probing alone. The probe attaches without recalibration, so switching between touch and scan modes is a tool change, not a setup.

How does the ProGage handle shop-floor conditions?

The arm carries IEC 60529 certification for dust and water ingress, and the carbon fiber structure provides thermal stability beyond what aluminum arms offer in environments with fluctuating temperatures. API backs the system with a 2-year warranty — double the typical coverage for portable CMM arms — which signals the intended operating environment: not a metrology lab, but the production line where temperature swings, airborne particulates, and occasional coolant mist are daily realities.
