In scenarios such as metrological testing and leveling, the accuracy of steel rulers directly affects the quality of subsequent work, and a reliable calibration device becomes a key aid. Based on the JJG1-1999 "Steel Ruler" calibration regulation, Pu Liang Tian Zhu has developed and launched the PTTC-GZ2 mechanical steel ruler calibration device and the PTTC-ZC3 digital steel ruler calibration device. Both products have their own focuses and meet the calibration needs in different scenarios.

<1>Common highlight: Adapting to diverse needs, balancing stability and flexibility

Both devices continue the practical design concept, maintaining consistent advantages in basic performance and structural design.

• Split table design:It can adapt to steel rulers of different thicknesses for detection, and can handle various specifications of workpieces without additional adjustments, improving detection efficiency.

• Tabletop positioning design:Balancing stability and flexibility, it can maintain the stability of the steel ruler position during the detection process and reduce measurement deviation caused by displacement. The core components have undergone strict calibration, and the width and spacing of the engraved lines are kept precise and consistent, providing a reliable foundation for the verification work.
