This caliper works well for machine shops that want better protection and smoother operation for frequent use around coolant and shop debris.
If your shop needs more protection from harsh environments, the iGaging 100-800-06 deserves attention. This 0-to-6-inch digital caliper pairs .0005-inch resolution with an IP67 rating, making it a compelling option where water and coolant resistance matter.
