Description
The 125–150 mm (5–6") IP65 Waterproof/Dustproof Digital Outside Micrometer from Insize 3108 series is built for tough environments where accurate outside measurements are needed. Its digital display delivers fast, repeatable readings with a 0.001 mm resolution, and the carbide measuring faces stand up to wear while helping maintain precision even after heavy use around fluids and coolants. The IP65 housing protects against dust and water, so you can work confidently in workshop or field settings without compromise.
Includes a spherical anvil for versatile measurement, setting standards are included (except 0–25 mm) to speed up calibration, and it runs on SR44 or LR44 batteries for easy maintenance.
- IP65 protection: Dustproof and waterproof design that performs reliably in damp, dusty environments and around machine fluids and coolants.
- 0.001 mm resolution with carbide faces: Delivers precise, repeatable measurements with wear-resistant tips for long tool life and dependable results.
- Easy digital operation with reliable measuring force: Simple on/off, set, and ABS/INC controls plus a ratchet for consistent contact pressure; includes a spherical anvil and calibration standards (except 0–25 mm) for fast, confident setup.
This digital outside micrometer helps you streamline inspection and troubleshooting across manufacturing, maintenance, and machining tasks. The IP65 protection and carbide faces deliver reliable readings in wet, dirty, or coolant-rich environments, while the 0.001 mm resolution and ratchet ensure precise, repeatable results every time. Easy setup—thanks to ABS/INC, a clear digital readout, and included calibration standards (where applicable)—means faster passes and less rework, improving workflow and overall quality.
