SR903-XXX-XX - Countersink Depth Gage - Spherical probe

A high precision digital gage for quick and accurate measurement of the countersink depth. The SR903 depth gage has a spherical type probe that contacts the inside wall of the countersink (see detail). The spherical probe mimics the ball over height method of measuring countersinks. This versatile gage can check a wide range of countersunk holes for virtually any flush head fastener. This gage can be used to set cages or micro-stops. The countersink angle can be calculated by using the SR903 Countersink Depth Gage in conjunction with the SR902 Countersink Diameter Gage.

Features:

• Measuring accuracy .0001 inch (.0025mm)
• Direct contact inside the countersink walls.
• Direct reading, no calculations or charts necessary.
• Large base configurations are available for curved surfaces.
• Accurate, repeatable, and reproducible.
• SPC ready via data port cable.
• Ease of use with minimal training.
• Eliminate costly rework.
• Gage and set block calibrated to NIST traceable standards.
• Unique serial numbers on gages, set blocks, and indicators.
• The components of our gages are made of heat-treated wear-resistant tool steels and micro-finished to ensure accurate and trouble-free operation.

Digital Indicators Features:

• LCD display with rotating bezel.
• Inch/ mm mode toggle capable.
• SPC data output ready via the data port.
• Upper and lower tolerance capable.
• User-selectable resolution (Mahr-Federal).
• Auto power off after 15 minutes of inactivity (Mahr-Federal).
• Lockout of setup preset (access key- Mahr-Federal, computer -Mitutoyo)
• Choice of indicators: Mahr-Federal, Mitutoyo, or Sylvac (please advise of your preference).
