The Hi-Lo Gauge is the big brother to the single use Hi-Lo gauge. This robust gauge is packed with features.
The Hi-Lo Gauge doubles as a way of checking cap height and measuring pipe wall thickness.
As a pipe fitter or welding inspector, two other dimensions you need to check are root gap and bevel angle. This Hi-Lo Gauge can measure these ensuring you comply with the Welding Procedure Specification and ensuring you minimise the chance of root fusion defects.
