INSIZE
INSIZE is a manufacturer of precision measuring instruments and metrology equipment, headquartered in Suzhou, China, with a global distribution network. The brand is known for offering a broad range of dimensional measurement tools that span from basic shop-floor gauges to more specialized inspection devices. 3G Electric supplies over 900 INSIZE SKUs, covering product families such as digital and dial calipers, indicators (dial, digital, and test), micrometers, height gauges, bore gauges, surface roughness testers, hardness test blocks, precision squares, V-blocks, and force gauges. These instruments are used across quality control, machining, tooling, and inspection applications in industries including automotive, aerospace, metalworking, and general manufacturing. INSIZE products are designed to meet common international accuracy standards, with many items offered in both inch and metric versions. For example, digital calipers in the 1118 series carry an IP67 rating for resistance to dust and water ingress, and are supplied with a certificate of inspection traceable to NIST. Dial test indicators like the 2380 series provide accuracy within ±0.0001 in, suitable for comparative measurements on machine tools or inspection fixtures. Hardness reference blocks such as the HDT-B-HV30D are calibrated for Vickers testers and come with documented hardness values. Precision steel squares in the 4745 series are made from stainless steel and offer inside accuracy of 0.0011 in, meeting the needs of machinists for angle verification. Magnetic V-blocks in the 6889 series are constructed from steel, rated to ASME 0 grade, and sold in pairs with a storage case, making them suitable for holding cylindrical workpieces during inspection or layout. 3G Electric supports the INSIZE line by maintaining stock of these items and providing detailed specification sheets, enabling engineers and procurement specialists to compare accuracy, range, resolution, and material properties before ordering. The catalog includes both standard and specialized configurations, such as calipers with pointed jaws for small grooves (1169 series) or indicators with flat backs for mounting in fixtures (2108 series). This breadth allows buyers to select tools that match their specific measurement tasks without overspecifying. All INSIZE products supplied by 3G Electric are new and sourced through authorized channels, ensuring traceability and compliance with the stated accuracy grades.
