Hi-Lo Gauge - Pocket measuring gauge

Pocket measuring gauge

The CAT1 Hi-Lo Gauge is made for demanding pipework environments where accurate fit-up directly affects weld quality. From pipe fabrication to industrial maintenance and welding inspection, its pocket format keeps the tool close to the operator, ready for quick checks without slowing down production.

This gauge is used to check internal pipe alignment after fit-up, measure internal misalignment before and after tacking, inspect pipe wall thickness, measure fillet weld leg length and verify butt weld crown height. It also includes go/no-go features for checking a 37.5° bevel and fit-up gap.

Its stainless steel construction provides durability for workshop and field use. Inch and metric scales support teams working with different fabrication or inspection standards.
