Mitutoyo 573-761-20 Digimatic Coolant Proof Tube Thickness Caliper 6 In with Thumb Roller

The Mitutoyo 573-761-20 is a 6-inch Digimatic digital caliper engineered specifically for measuring tube wall thickness. Its coolant-proof construction makes it ideal for use in demanding shop floor environments where exposure to cutting fluids and coolants is common.

Key Features:

• Tube-thickness measuring design: The main scale jaw features a round bar profile that facilitates smooth movement along curved tube surfaces, enabling accurate wall thickness measurement
• Coolant proof: Sealed against coolant and fluid ingress, ensuring reliable performance in wet machining environments
• 6-inch (150 mm) measuring range suitable for a wide variety of tube and workpiece sizes
• Digimatic digital readout for fast, easy, and precise readings with minimal operator error
• Thumb roller for smooth, controlled jaw movement and one-handed operation
• Mitutoyo's industry-leading build quality and measurement accuracy

The 573-761-20 is part of Mitutoyo's trusted Digimatic series, widely used by machinists, quality control inspectors, and engineers. Its specialized tube-thickness jaw geometry makes it the preferred choice when standard calipers cannot reliably seat against curved or tubular workpieces.
