75-100mm 3-4" IP65 Waterproof/Dustproof Digital Outside Micrometer - 3108 Series (Insize)

The 75-100 mm (3-4") IP65 Waterproof/Dustproof Digital Outside Micrometer from Insize 3108 Series is built to deliver fast, repeatable measurements in challenging environments. With a sealed IP65 housing, it stays protected against dust, water splash, and common shop fluids, so you can measure confidently near machines, coolant lines, and wet work areas. The carbide measuring faces resist wear for longer tool life, helping you get accurate readings over many use cycles.

• IP65 protection for tough environments: Sealed construction guards against dust and water spray, reducing downtime and enabling reliable measurements around fluids and coolants.
• 0.001 mm resolution with easy digital readout: Precise, clear measurements displayed on a digital LCD, with ABS/INC capability and simple on/off and set controls for quick, consistent readings.
• Durable carbide faces with spherical anvil and included standards: Wear-resistant faces plus a spherical anvil support a wide range of part geometries, and setting standards (except 0-25 mm) make calibration straightforward and repeatable.

Designed for engineers, machinists, technicians, and hobbyists, this digital outside micrometer delivers dependable performance in everyday shop tasks and in environments where fluid exposure is common. It speeds up setup, improves measurement repeatability, and provides the confidence to achieve precise tolerances on a busy production line or in a detailed inspection routine.
