1.4 Way Measuring Tool for Internal, External, Depth and Step measurements Key benefits Versatile allinone tool that handles internal, external, depth and step measurements, reducing the need for multiple gauges. Locking screw supports batch measurements and go/nogo quality checks, helping maintain consistent tolerances across parts. Thumb screw allows smooth carriage movement for more precise measurements and finer control. Extra large LCD display enables fast, clear readings for quick inspection and reduced reading errors. What it does Provides four measurement capabilities in a single instrument: internal diameter, external diameter, depth, and step measurements. The locking screw prevents unwanted carriage movement during batch testing, improving repeatability. The thumb screw facilitates controlled carriage travel for precise measurement increments. Large LCD display presents readings clearly, aiding reliable interpretation in workshop or production environments. Applications and use scenarios Quality control in batch production: use for quick, repeatable internal, external, depth, and step measurements across multiple parts, with go/nogo checks enabled by the locking screw. Machine setup and inspection in a workshop: precisely set workpieces and fixtures by smoothly rolling the carriage with the thumb screw to obtain accurate readings. Onsite maintenance and : verify tolerances of components with combined measurement capability, ensuring components meet specified dimensions before reassembly.
