MITUTOYO IP65

MITUTOYO, founded in 1934 in Tokyo, Japan, is a manufacturer of precision measurement instruments. The IP65 series of digital outside micrometers is designed for use in environments where exposure to coolant, dust, and moisture is routine. These micrometers feature an IP65-rated housing, meaning they are sealed against dust ingress and protected against low-pressure water jets from any direction, making them suitable for direct use on machine tools or in wet grinding areas. The product line includes models with and without SPC (Statistical Process Control) output, covering measuring ranges from 0 in to 6 in (0 mm to 101.6 mm) in various increments. Key specifications include a resolution of 0.00005 in / 0.001 mm for standard models and 0.000005 in / 0.0001 mm for higher-accuracy variants, with accuracy ratings ranging from ±0.00002 in to ±0.0001 in depending on the range. All IP65 models feature an inch/metric conversion function and a large, easy-to-read LCD display. The micrometers are constructed with a hardened steel frame and a carbide-tipped spindle and anvil for wear resistance. Some models come with a Certificate of Inspection, confirming traceability to national standards. 3G Electric supplies the full range of MITUTOYO IP65 micrometers, including both standard and calibration-certified versions, to support maintenance, quality control, and production environments where reliable measurement under harsh conditions is required. The company offers global logistics support, enabling procurement teams worldwide to source these instruments with consistent lead times and documentation.

Frequently asked questions

Common questions about MITUTOYO IP65 from 3G Electric.

What does the IP65 rating mean on MITUTOYO micrometers?

The IP65 rating indicates that the micrometer housing is dust-tight (first digit 6) and protected against low-pressure water jets from any direction (second digit 5). This means the instrument can be used in environments with airborne particulates, coolant splashes, or washdown procedures without compromising internal electronics or mechanical function. It does not mean the micrometer is submersible or suitable for high-pressure washdown.

What is the difference between MITUTOYO IP65 micrometers with and without SPC output?

Models with SPC output (e.g., MPN 293-330-32) include a data output port that allows connection to external data collection systems, such as SPC software or data loggers, for real-time measurement recording and analysis. Models without SPC output (e.g., MPN 293-342-32) lack this port and are intended for manual reading and recording. Both types share the same IP65 protection, resolution, and accuracy specifications for their respective ranges.

What measuring ranges are available for MITUTOYO IP65 micrometers?

The MITUTOYO IP65 digital outside micrometer series covers ranges from 0 in to 1 in (0 mm to 25.4 mm) up to 5 in to 6 in (127 mm to 152.4 mm), with intermediate ranges such as 2 in to 3 in and 3 in to 4 in. Each range is available in both SPC and non-SPC variants. The specific range you need depends on the part dimensions you are measuring; for example, a 0 in to 1 in model is suitable for small components, while a 5 in to 6 in model is used for larger shafts or bores.

Can MITUTOYO IP65 micrometers be used with a Certificate of Inspection?

Yes, certain models (e.g., MPN 293-346-32CAL, 293-348-32CAL) are supplied with a Certificate of Inspection, which documents the actual measurement results and traceability to national standards. This is useful for quality assurance programs that require documented calibration evidence. Standard models without the 'CAL' suffix do not include this certificate but can be ordered with one upon request through 3G Electric.

What is the resolution and accuracy of MITUTOYO IP65 micrometers?

Standard IP65 models have a resolution of 0.00005 in / 0.001 mm and an accuracy of ±0.00005 in for ranges up to 2 in, and ±0.0001 in for larger ranges. Higher-accuracy models (e.g., MPN 293-230-32) offer a resolution of 0.000005 in / 0.0001 mm with an accuracy of ±0.00002 in, but these are not IP65-rated. Always verify the specific model's specifications before ordering.
