OCTAGON Dial Calibration Tester

The manufacturing tolerance in almost all the Industries are becoming stringent due to increased awareness of quality. This also calls for high accuracy components in
Precision Assemblies and Subassemblies. The Quality Control Department, therefore is loaded with the periodic calibration of various measuring instruments, since the accuracy of the components depends largely on the accuracy of measuring instruments. In other words the periodic calibration of shop floor Precision Instruments like Plunger type Dial Gauges, Back Plunger type Dial Gauges, Lever type Dial Gauges and Bore Gauges is inevitable and is a regular feature in many companies of repute. The practice of Periodic Calibration is of vital importance for Quality Assurance as well as cost reduction.
