Starrett 199Z Master Precision Level 15" Base .0005"/ft Sensitivity

The Starrett 199Z Master Precision Level is a professional-grade machinist's level engineered for the precise setup, checking, and testing of machinery of all types. With a 15" (380mm) ground reference base and a sensitivity of .0005" per foot (0.04mm per meter), this instrument delivers the accuracy that machine operators, setup technicians, and maintenance professionals demand for critical alignment work.

The main vial is ground and graduated to 10-second accuracy, with seven graduations on each side of the bubble for clear, repeatable readings. An auxiliary lateral vial assists in horizontal positioning, giving the user simultaneous longitudinal and lateral level information in a single instrument. Vials are strategically positioned to minimize the risk of breakage, and the fool-proof adjustment mechanism prevents tampering once calibration is set.
