Value Collection 621-8312 Electronic Height Gage 12 in

Product Description

The VALUE COLLECTION 621-8312 is an electronic height gage designed for precision linear measurement in toolroom, machining, and inspection environments. It measures surfaces and step heights up to 12 inches (300 mm) with a resolution of 0.001 inches (0.0100 microns), making it suitable for close-tolerance work. Readings are displayed on a built-in LCD screen for fast, clear readout. The unit weighs 9.1 pounds, indicating a solid, stable base construction appropriate for surface plate use. Machinists, quality control technicians, and tool and die professionals are the typical end users.

This height gage is used for layout and inspection tasks on surface plates in machine shops, manufacturing facilities, and quality labs. It is well suited for scribing part features, checking part height against a datum, and verifying dimensional tolerances during in-process or final inspection. The dual-unit capability covering both inch and millimeter readout makes it practical in shops working to mixed drawing standards.

Compatibility

Designed as a standalone electronic height gage for use on standard surface plates in toolroom and inspection applications.

Installation Notes

Electronic height gages require no permanent installation and are set up by a machinist or quality technician on a flat, clean surface plate. Ensure the surface plate and gage base are free of chips and debris before use to avoid false readings. Handle the measuring column and scriber assembly carefully to protect calibration. Follow the manufacturer's zeroing procedure before each measurement session.
