The Mitutoyo ABSOLUT Digimatic CoolantProof Caliper is a precision measuring instrument designed for demanding industrial environments. With an IP67 protection rating, it is dustproof and can withstand temporary immersion in water up to 1 meter deep for 30 minutes. The measuring range of 0-150 mm allows for accurate external measurements, internal measurements, and depth measurements using the round depth gauge. The ABSOLUT sensor system eliminates the need for zeroing upon startup and retains the last position measurement even after battery replacement. Made from durable materials, this caliper provides reliable performance in workshop environments with coolants, oils, and water. The digital display clearly shows measurements in millimeters or inches with a resolution of 0.01 mm/0.0005 inches. The ergonomic design includes a thumb roller for smooth operation and an output connection for data transfer to compatible devices. This model, designated as 500-709-20, is ready for immediate use as a single unit for quality control, machining, and manufacturing applications where precise dimensional verification is essential. The CoolantProof construction ensures long-term functionality even when in contact with industrial fluids, making it suitable for metalworking, automotive repair, and mechanical engineering tasks. The battery life is optimized for extended use, and the display automatically shuts off to save energy. The stainless steel measuring surfaces offer wear resistance and maintain calibration accuracy over time. This instrument meets the needs of professionals who require reliable measuring tools that can withstand challenging environmental conditions and deliver consistent, repeatable results.
