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 for 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, for 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, for gap and other dimensions. Widely used in construction, railway, electric power, ceramic sanitary ware, automobile windshield and mold for gap and other gaps. Specifications: Material: Carbon steel, matt chrome-plated surface Measuring Range: 1-15mm (division value 0.1mm), 0.5-10mm (division value 0.05mm), 0.4-6mm (division value 0.05mm) Packge included: 1 * Taper Gauge Welding Feeler Wedge Gauge
