1-15mm 0.5-10mm 0.4-6mm Wedge Feeler Gauge Crack Flatness Layout Insert Wedge Gauge Welding Taper Measurement Features: Precise measurement: It adopts carbon steel for mechanical structure and chrome plating on the surface, which can ensure the accuracy and stability for long-term use. Simple operation: Measure the inner dimension with thickness, insert the diagonal ruler into the gap directly, and display the measurement results directly. Laser scale: Marking with a laser marking machine, the scale is clear and delicate, not easy to wear, long-term use, the scale is still clear and discernable. Important parameters: Suitable for on-site measurement, gap measurement in the range of 1-15m, 0.5-10mm, 0.4-6mm; division value: 0.10mm, 0.05mm, 0.05mm Application: Applicable to the measurement of groove, gap and other dimensions. Widely used in construction, railway, electric power, ceramic sanitary ware, automobile windshield and mold gap and other gaps.
