MAHR

MAHR digital indicators available through 3G Electric cover measurement ranges from 0.00001 in to 0.039 in (0.001 mm to 1 mm) for inductive comparators, and up to 0 in to 1 in (0.001 mm to 25 mm) for standard digital indicators. Specific models include ranges such as 0 to 0.5 in (0 to 12.5 mm) and 0 to 0.5 in (0 to 12.7 mm), with inch/metric switching. Accuracy is typically 0.002 mm for digital indicators, and resolution can be as fine as 0.00001 in. These ranges suit both fine and general dimensional inspection tasks.

MAHR digital indicators supplied by 3G Electric are available with IP42 or IP54 ratings. IP42 provides protection against solid objects larger than 1 mm and dripping water, suitable for controlled environments. IP54 offers protection against dust ingress and splashing water, making it appropriate for shop-floor use where coolant or particulate exposure is possible. The specific rating depends on the model, with IP54 versions often preferred for harsher production conditions.

Yes, MAHR horizontal dial test indicators from 3G Electric typically include a spanner wrench and a Certificate of Conformance. For example, models like the MAHR Horizontal Dial Test Indicator (MPN 4305950) and MPN 4306960 come with these items. The spanner wrench is used for adjusting the bezel or mounting, and the certificate confirms the instrument meets specified accuracy standards. Additional accessories may be available separately depending on the application.

MAHR mechanical dial comparator gauges, such as the model MPN 4334000, offer an accuracy of ±1 micron. These gauges feature a 50-0-50 dial reading, allowing for comparative measurements with high sensitivity. The mechanical design eliminates the need for batteries, making them reliable for long-term use in quality control labs. The ±1 micron accuracy is suitable for precision comparisons of machined parts within tight tolerances.

Yes, MAHR digital indicators stocked by 3G Electric feature inch/metric switching capability. This allows operators to toggle between imperial and metric units without recalibration. The display resolution adjusts accordingly, with typical resolutions of 0.00002 in or 0.001 mm. This dual-unit functionality is standard across most digital indicator models, including those with removable flat backs, facilitating use in global manufacturing environments.

MAHR digital indicators from 3G Electric come with a removable flat back, which allows for flexible mounting on stands, fixtures, or comparator bases. The flat back can be detached to expose a dovetail or other mounting interface, depending on the model. This design supports both vertical and horizontal orientation, making the indicators adaptable to various inspection setups. The 58 mm diameter housing is common across many models, ensuring compatibility with standard mounting accessories.
