- Solid, transparent acrylic blocks are used for the body's cutting and precise machining, enabling thorough visual examination.
- The float is easier to see on a white background, which improves reading accuracy.
- The material has direct reading scales hot stamped onto it, extending the life of the product and removing the need for laborious conversions.
- A very repeatable tapered bore made by precision machining is possible.
- Minimal installation expenses with options for end or back connections.
