Scanning probe family
SC30 & SC80 Scanning Probes
Two contact-scanning platforms for different stylus and access requirements—from compact, everyday CMM scanning to long and heavy stylus configurations.
Probe, stylus, head, controller, software, and application details are reviewed together.
Choose around stylus reach and the feature
Review the compact SC30 and long-stylus SC80 platforms, compare their limits, then plan the head, controller and changing setup.
Select by application
Two scanning platforms. Two different jobs.
Start with stylus reach, stylus mass, feature access, measurement function, and the CMM control workflow.
Long & heavy stylus scanning
SC80
Continuous analog-output scanning probe designed for long and heavy stylus configurations and internal-part features.- Up to 600 mm stylus length
- Up to 1,000 g stylus weight
- Automatic weight balancing
SC30 compact scanning probe
Compact, modular scanning for varied stylus lengths
The SC30 family is designed for both touch-trigger and continuous scanning measurement. A high-sensitivity Hall sensor supports responsive measurement performance, while automatic magnetic coupling supports use with the CZ10M-S and other compatible automatic probe heads.
Two measurement modes
Touch-trigger measurement and continuous scanning.
Hall sensor technology
High-sensitivity displacement sensing for responsive measurement.
Automatic magnetic coupling
Mounts to CZ10M-S and other compatible automatic probe heads.
Three matched configurations
Leaf-spring configurations aligned to specified stylus ranges.

Model comparison
Choose the probe around the measurement task
SC30 and SC80 are distinct product platforms. The right choice depends on stylus configuration, access, measurement function, and system integration.
| Selection factor | SC30 family | SC80 |
|---|---|---|
| Primary positioning | Compact high-precision scanning family | Long and heavy stylus analog scanning |
| Measurement functions | Touch-trigger measurement and continuous scanning | Single-point probing, self-centering measurement, and continuous scanning |
| Stylus reach | Up to 400 mm | Up to 600 mm |
| Measuring range | ±0.5 mm | ±1.0 mm |
| Resolution | 0.1 µm | 0.01 µm |
| Automation feature | Automatic magnetic coupling for CZ10M-S and compatible heads | Automatic stylus clamping and automatic weight balancing |
| Best-fit applications | Compact scanning, modular stylus-length selection, routine CMM scanning workflows | Long/heavy stylus access, internal features, and deeper-access applications |
Final compatibility and performance must be confirmed for the complete CMM configuration, including probe head, controller, software, stylus assembly, rack strategy, and acceptance requirements.
Configuration review
What PeakMerit confirms before quoting
A scanning probe is selected as part of a complete measurement system—not as an isolated component.
Stylus reach and mass
Required length, extension stack, ball diameter, access direction, and total assembly weight.
Feature access
Internal bores, deep pockets, free-form surfaces, self-centering requirements, and collision clearance.
Head, control, and software
Probe-head interface, controller workflow, scanning capability, software capability, and rack compatibility.
Calibration and acceptance
Stylus qualification, rack strategy, reference sphere, test method, and project-specific acceptance criteria.
