Gauges feature heavy-duty sensing elements, stainless cases, and are typically used in more demanding applications. These gauges usually have greater accuracy requirements over general purpose gauges. The industrial gauge is built for extended life and designed for harsh environments. They are used for process control; for measurement of flow, volume, density, or material presence; and may be placed in locations unsuitable for continuous human presence. They are typically used in more demanding applications. Gauges do not indicate the exact value of the inspected dimension on the work. They are very efficient and useful.
