What this caliper is and who uses it

The General Tools 147 is a 6 inch stainless steel digital caliper built for machinists, engineers and hobbyists who need quick unit changes. It reads inside, outside, step and depth dimensions on a high contrast tri mode display. The tool ships new in a foam padded plastic case for protected storage when not in use.

Measurement limits of the tri mode display

The display switches between decimal inches, fractional inches and millimetres at the touch of a button with guaranteed accuracy to .001 inch. A flashing readout warns when the battery is low so readings remain trustworthy. No other measurement standards or output protocols are provided by this instrument.

Build quality and everyday handling

The hardened stainless steel body resists shop wear while the large digits reduce eye strain during repeated checks. The included foam lined case keeps the jaws clean and aligned between jobs. Users who need data logging or wireless transfer will find this model lacks those connectivity features.
