A. Product Overview
R-Tek Micrometers are designed for industrial users who require precise measurement of small component dimensions.
The R-Tek RK-501 is a manual micrometer with a 0 to 25 mm measuring range and 0.01 mm resolution. It features an aluminum or steel construction, durable mechanical design, clear scale markings, ergonomic handling and battery free operation.
The R-Tek RK-504 is a manual micrometer covering a 50 to 75 mm measuring range with 0.01 mm resolution. It is designed for industrial applications and features an aluminum construction, clear scale markings, durable mechanical operation and ergonomic handling.
The R-Tek RK-507 is a digital micrometer with a 25 to 50 mm measuring range and stated accuracy of ±0.003 mm. It incorporates a high contrast LCD display, instant digital reading, zero setting function, dual unit switching, high repeatability and rapid measurement capability.
Together, these models provide options for users who prefer either traditional mechanical measurement or convenient digital indication.
B. Working Principle
A micrometer measures a component by converting the controlled movement of a precision screw into a dimensional reading.
In a manual micrometer such as the RK-501 or RK-504, the component is positioned between the measuring surfaces. Rotating the micrometer mechanism gradually moves the spindle toward the component. The resulting dimension is then determined using the graduated mechanical scale.
The RK-501 and RK-504 use mechanical measurement and therefore operate without batteries. Both models specify a resolution of 0.01 mm.
In a digital micrometer such as the RK-507, spindle movement is electronically converted into a numerical value and displayed directly on the LCD screen. This eliminates the need to manually interpret scale markings. The RK-507 also provides zero setting and dual unit switching for convenient measurement.
The explanation of spindle and screw operation above describes the standard operating principle of outside micrometers. The listed ranges, resolution, accuracy and electronic functions are taken from the supplied product listings.
C. Why R-Tek Micrometers Are Used
R-Tek Micrometers are used when accurate dimensional inspection is required for manufactured or machined components. They are particularly useful where ordinary rulers or general measuring tools cannot provide sufficient resolution.
Typical applications include:
- Measuring external component diameter
- Measuring material thickness
- Checking machined parts
- Inspecting shafts, rods and similar components
- Production quality inspection
- Workshop dimensional measurement
- Engineering inspection
- Manufacturing process verification
- Component comparison and tolerance checking
- Maintenance and fabrication measurement
The manual RK-501 and RK-504 provide simple mechanical measurement with battery free operation, while the RK-507 provides direct digital readings and additional functions for faster measurement.
