The SPI 11-963-6 is an electronic digital caliper designed for precise dimensional measurement in shop, field, and maintenance environments. It measures from 0 to 8 inches with a resolution of 0.0005 inches and an accuracy of 0.0010 inches, making it suitable for close-tolerance work across HVAC, plumbing, and general mechanical trades. The caliper body and jaws are constructed from hardened stainless steel, providing corrosion resistance and durability under daily use. An IP54 rating protects the electronics against dust ingress and splash exposure. A data output port allows readings to be sent to compatible data collection systems or SPC software, which is useful in quality-control workflows.
This caliper is used wherever technicians need reliable inside and outside dimensional measurements on the job. Typical applications include measuring pipe outside diameters, fitting inside diameters, shaft dimensions, and component depths during installation or inspection. The included depth measurement rod extends its utility beyond jaw-based measurements. It is appropriate for residential and light commercial service work as well as shop inspection tasks. The caliper ships with a protective case, keeping it safe during transport between job sites.
Designed as a general-purpose electronic caliper suitable for dimensional measurement tasks across HVAC, plumbing, electrical, and mechanical service trades.
No permanent installation is required. Before use, verify the caliper is zeroed with jaws fully closed. Keep the measuring surfaces clean and free of debris to maintain accuracy. Avoid exposing the caliper to prolonged immersion or direct fluid streams beyond its IP54 splash rating.
