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.

Frequently asked questions

Common questions about INSIZE from 3G Electric.

What accuracy grade do INSIZE magnetic V-blocks like the 6889-2 and 6889-4 meet?

INSIZE magnetic V-blocks in the 6889 series are rated to ASME 0 grade. This means they are manufactured to a high precision level suitable for inspection and layout work, with tight tolerances on parallelism, squareness, and V-groove alignment. The blocks are made from steel and sold as a pair, each including a storage case to protect the working surfaces.

Does the INSIZE digital caliper model 1118-150R include SPC output?

No, the INSIZE digital caliper model 1118-150R does not include SPC output. It is designed for general-purpose measurement without data transmission capability. The caliper has an IP67 rating, making it resistant to dust and temporary immersion in water, and it comes with a certificate of inspection traceable to NIST. Accuracy is ±0.0012 in over the 0 to 6 in / 0 to 150 mm range.

What is the measurement range and accuracy of the INSIZE horizontal dial test indicator 2380-301?

The INSIZE horizontal dial test indicator model 2380-301 has a measurement range of 0 to 0.008 in and an accuracy of ±0.0001 in. It features a horizontal and tilted-face style with a 5/32 in clamp for mounting. The indicator includes a short form certificate of inspection with NIST traceability, confirming its calibration.

Are INSIZE hardness test blocks like the HDT-B-HV30D supplied with a calibration certificate?

Yes, the INSIZE hardness test block model HDT-B-HV30D is a reference block for Vickers hardness testers and is supplied with documented hardness values. While the product listing indicates it is a hardness reference block, the specific certification details (e.g., certificate type) should be verified with the supplier. Typically, such blocks include a certificate stating the measured hardness and traceability.

What material is the INSIZE precision steel square 4745-1120 made from, and what is its inside accuracy?

The INSIZE precision steel square model 4745-1120 is made from stainless steel, which provides corrosion resistance and dimensional stability. Its outside dimensions are 4-45/64 x 3-7/64 in, and it has an inside accuracy of 0.0011 in. The square is supplied in a box for protection during storage and transport.

Can the INSIZE digital indicator 2108-10EF be used in both inch and metric modes?

Yes, the INSIZE digital indicator model 2108-10EF is switchable between inch and metric units. It has a measurement range of 0 to 0.5 in / 0 to 12.7 mm and an accuracy of ±0.0015 in. The indicator features a back-plunger design with a flat back, making it suitable for mounting in fixtures or stands. Resolution is 0.0005 in / 0.01 mm.
