Overview
The Z-Mike Pro is a non-contact laser micrometer for dimensional inspection of precision parts on the shop floor and in metrology labs. It measures diameter, ovality, effective cutting diameter, taper and total indicated runout (TIR) without touching the part, avoiding mechanical deformation and operator influence. Models deliver up to ±0.5 µm accuracy and model-dependent repeatability as specified below. Measurements are traceable to national standards (NIST).

Features & Benefits

• Patented optical design and electronics for consistent accuracy and repeatability.
• Automatic calibration and temperature compensation for stable results in production environments.
• Measurement precision insensitive to surface finish (gloss, matte, color) and to ambient stray light.
• Non-contact technique eliminates operator-induced measurement error and avoids part distortion.
• No precise centering required—minimal setup across a wide range of part sizes.
• Rugged sealed cast housing for dust- and moisture-prone factory environments.
• Large high-resolution touchscreen with intuitive UI; store and recall multiple product programs.
• Integrated I/O for straightforward integration with automated handling and motion control.
