Precision Measuring Instrument

In-process
Post-process
Wide range measurement
LVDT gauge
High Accuracy
Compact Ultra-High Precision Measuring Head (Size Shift)
PULCOM Mini Σ-V13
Features
Compact with a Wide Measuring Range
Despite being compact, the need to change the setup is eliminated with a 13 mm measuring range.
High Precision, High Rigidity, and High Durability
Our original fulcrum mechanism delivers high precision even when a size shift is required.
Resistant to Temperature Change
The improved performance of the sensor minimizes the change in measured values that are caused by variations in the ambient temperature.
Workpiece Scratch Prevention
The improved air retract mechanism provides a soft landing on the workpiece.
