Specializing in rules and precision | Putian Tongchuang launches image measuring instrument Ec calibration dedicated step gauge
Date: 2025-11-24Read: 1
To meet the increasing demand for accuracy and efficiency in the calibration of image measuring instruments, Putian Tongchuang has officially launched a dedicated step gauge for Ec calibration of image measuring instruments. This step gauge is a standard instrument that complies with the JJF 1318-2011 Calibration Specification for Image Measuring Instruments. The main purpose is to calibrate the consistency (Ec) of the measurement results of the image measuring instrument at different cross-sections (Z-axis heights), effectively evaluate the indication error of the instrument in the entire measurement space, and is a key tool to ensure the accuracy performance of the instrument.
Product Core Value:
Strict compliance: The design and manufacturing comply with the requirements of JJF 1318-2011 Calibration Specification for Image Measuring Instruments, eliminating doubts about the applicability of the standard during the calibration process.
Convenient and efficient: equipped with embedded positioning targets, making the target search and positioning during the calibration process fast and intuitive.
This product is manufactured with precision according to the following technical requirements.
1. Technical requirements for specialized step gauge substrate:
| total length | Not less than 4/5 of the diagonal of the working stroke of the measured image measuring instrument |
| Height difference between two steps | Not less than 1/2 of the instrument's Z-axis travel |
| width | Not less than 50mm |
| Bottom flatness | ≤ 0.01mm (concave) |
| Flatness of the step surface at the groove | ≤ 0.005mm |
2. Requirements for Embedded Target Technology:
| Bottom flatness | ≤ 0.005mm |
| Marking width | ≤ 0.005mm |
The Ec calibration specific step gauge launched by Putian Tongchuang is not only a product, but also a reflection of our commitment to providing professional, reliable, and efficient measurement solutions for the industry. We believe that it will become a valuable tool for you when performing Ec calibrationCommonly used and professionally reliable assistance.
