R-Tek Digital Depth & Thickness Gauges

A. Product Overview

R Tek Digital Depth and Thickness Gauges provide convenient digital measurement for applications where dimensional accuracy is important.

RK 521 Digital Depth Gauge
The RK 521 is designed for depth measurement of holes, grooves, slots, recesses and similar features. It offers a digital display for easy reading and supports measurement in millimetres and inches.

RK 522 Digital Thickness Gauge
The RK 522 is designed for measuring the thickness of suitable materials such as paper, plastic, leather, films and other thin materials. Its digital display allows users to check thickness quickly during inspection and quality control.

Both models are suitable for routine industrial measurement, production checking and laboratory use.

B. Working Principle

R Tek Digital Depth and Thickness Gauges work by converting mechanical movement into a digital measurement value.

In the RK 521 Digital Depth Gauge, the measuring rod or contact point moves according to the depth of the hole, slot or recess being checked. The internal electronic measuring system converts this displacement into a digital reading shown on the LCD display.

In the RK 522 Digital Thickness Gauge, the material is placed between the measuring contact surfaces. The movement caused by the material thickness is detected by the internal measuring mechanism and converted into a digital value.

Digital indication helps reduce reading errors that can occur with conventional analogue scales.
