The Groz Granite Comparator Stands are a highly accurate and reliable tool for dimensional inspection in industrial settings. The stands are manufactured from the highest quality black granite with a uniform texture and colour, providing the stability and accuracy required for precision measurements. Granite is an inherently stable and non-magnetic material with a minimal thermal expansion coefficient, making it ideal for applications that require high levels of co-planarity, perpendicularity, parallelism, flatness, and straightness. 

The rigid granite base is free from burrs, pileups, rust, and deterioration over time, ensuring that the stand provides consistent and accurate results for many years. These comparator stands are ideal for use in a variety of industries, from tool rooms and machine shops to welding shops and construction sites. Their robust construction and high accuracy make them a valuable addition to any measurement and inspection toolkit.
