Lightweight yet rugged enough for production, Johnson Gage Portable Thread Inspection Systems share many of the attributes of the Bench Systems.  Available in two different series, all Portable Inspection components are carefully balanced by design to reduce operator fatigue and simplify the inspection process.  A coaxial in-line gage/product center of gravity maximizes repeatability and reproducibility.  Self-supporting and self-centralizing. All Systems offer an up-front indicator position for maximum visibility and ease of use.
