Product Overview
The Mitutoyo 500-703-20 is a robust, high-performance digital caliper designed for use in harsh workshop environments where exposure to coolant, water, dust, or oil is expected. It features an IP67 protection rating, meaning it is completely dust-tight and can withstand temporary immersion in water without sustaining damage. This “Coolant Proof” model utilises Mitutoyo’s proprietary ABSOLUTE electromagnetic induction linear encoder, which ensures that the zero point is never lost, even when the power is turned off. With a measuring range of 0 to 200mm, this unit offers greater versatility than standard 150mm calipers while maintaining an ergonomic form factor for easy single-handed operation.
