About INSIZE

INSIZE is a manufacturer of precision measuring instruments and metrology tools, with a product range that includes micrometers, calipers, indicators, hardness testers, surface roughness testers, ultrasonic thickness gauges, straight edges, squares, and force gauges. The brand is known for offering a broad catalog of dimensional measurement and inspection tools that serve machining, fabrication, quality control, and maintenance operations. INSIZE products are used across industries such as automotive, aerospace, energy, and general manufacturing, where accurate verification of part dimensions, surface finish, and material thickness is required. 3G Electric supplies the INSIZE line as part of its industrial equipment portfolio, providing access to over 900 SKUs. The product families cover both basic hand tools and electronic instruments. For example, digital outside micrometers without SPC output, such as the 3109-25A, offer a range of 0-1 in (0-25 mm) with 0.00005 in (0.001 mm) resolution and ±0.002 mm accuracy, and include inch/metric conversion. Surface roughness tester reference specimens, like the ISR-RS528X, are nickel electroformed and provide a roughness value of 0.5 µm (20 µin) for calibrating surface roughness testers, conforming to ISO 5436-1:2000. Handheld Leeb hardness testers, such as the ISH-SPHD, are designed for non-destructive testing of copper materials and measure in scales including HRB, HRC, HB, HLD, HS, HV, and MPa, with an accuracy of 1 HS and tolerance of ±6 HLD. Ultrasonic thickness gauges, like the ISU-800D, offer a thickness measurement accuracy of ±0.02 mm/0.3%H (whichever is greater) and include a couplant, transducer (ISU-P06), and USB cable. Stainless steel straight edges, such as the 4700 series, are available in various lengths with tolerances from 2.2 to 3.2 microns, featuring satin finishes, beveled edges, and dual metric/SAE graduations. These tools are used for checking flatness and straightness in machining, fabrication, and quality inspection. 3G Electric supports the INSIZE line by stocking a wide selection of these instruments and providing technical specifications, calibration options, and application support to help buyers select the appropriate tool for their measurement tasks. The company serves a global customer base, shipping INSIZE products to maintenance managers, plant engineers, and procurement specialists worldwide. With a focus on dimensional metrology, INSIZE tools are suited for incoming inspection, in-process verification, and final quality assurance. The availability of both metric and imperial units, along with various accuracy grades, allows users to match instruments to specific tolerances and standards. 3G Electric's catalog includes INSIZE products that are not certified by default but can be supplied with calibration certificates upon request, depending on the model. This flexibility supports quality systems that require traceable measurements. The brand's product range also includes force gauges, squares, and other inspection tools, making it a comprehensive source for metrology needs in industrial settings.
