JFA angle standard 90 degrees, triangular 400x250 mm, LAB 0.001 mm accuracy

Application

For simple and precise checking of the 90° angle. Ideal for use on hard stone bases, e.g. for checking straightness in vertical height measuring devices; also suitable as a contact surface for large components. Also suitable for checking the 90° angle e.g. in coordinate measuring instruments and machine tools.

Execution

• Carefully selected and flawless South African hard stone material – Diabas.
• with through-bore(s) for weight reduction
• Exactly 2-sided. The two precisely shaped surfaces are finely machined to a high-quality finish to be flat and at exact angles to one another. The remaining surfaces are finely machined
• LAB accuracy: surface finely ground and lapped to maximum fineness
• can be used horizontally and vertically
• Calibration certificate included in the scope of delivery. measurement results are based on national standards
• DAkkS calibration certificate available on request

Delivery

Calibration certificate. Measurement results are based on national standards from the German National Metrology Institute in Brunswick, Germany.
