The Western Gage WGC Micro II Air Gage Readout is a high-precision, microprocessor-based instrument designed for fast, accurate measurement of critical part dimensions. Whether you are inspecting internal and external diameters, tapers, or geometric features like concentricity and parallelism, this air gage comparator delivers reliable, high-resolution results for demanding production environments .
Key Features & Benefits
- High-Resolution Display: Features a bright color digital display coupled with a bar graph for easy visualization of part dimensions relative to tolerance limits .
- Ultra-Fine Resolution: Provides resolution down to 5 microinches (0.1 microns), making it ideal for tight-tolerance applications such as medical implants, aerospace components, and machine tool spindles .
- Versatile Connectivity: Equipped with both RS-232 and USB serial data outputs, allowing seamless connection to computers, data collection systems, or SPC software for detailed process analysis .
- Multi-Channel Capability: The Micro IIi series is capable of handling up to four inputs, allowing for complex gaging setups and inspection of multiple features in a single cycle .
- Auto-Calibration: Simplifies the setup process with automatic calibration when using master gages, reducing operator error and ensuring measurement integrity .

Applications
The Western Gage Micro II is a versatile dimensional air gage system suitable for a variety of precision measurement tasks:
- Taper Measurement: Specifically designed to measure machine tool spindle tapers (e.g., Cat, V-flange), tool holders, and medical implant tapers .
- Dimensional Inspection: Ideal for high-volume inspection of bores (I.D.) and shafts (O.D.) where speed and accuracy are critical .
- Geometric Inspection: When paired with custom tooling, it can inspect flatness, straightness, and parallelism more efficiently than CMMs or roundness testers
