Decibels Meter K475

K475 Moving Coil Meter, calibrated in dBs.

• Diameter across flange, 4.75".
• Diameter across the body, 4.125".
• Scale length (single range), 4.25".
• The angle of Arc, 95 degrees.

This high-grade line of Meters (5" class) is of the protected Dial pattern and is fitted with a modified standard movement and special Alnico magnet. The convex face of the highly polished bakelite case is symmetrically curved. This feature adds considerably to the Instrument's appearance and at the same time enables the movement to be raised high enough, with respect to the Dial, for a straight through needle of minimum weight to be fitted.

The long, clearly marked scale, in conjunction with the knife edge or arrow pointer, reduces parallax errors to a minimum. No flange screws are required for mounting. This is accomplished using the special back bracket provided.
