ANSI / AGD Group 0 - Mahr Federal Series A and N

Where available space prohibits the use of a larger dial indicator.

Dial: approx. 1.250in diameter with soft-green tint (A)
approx. 32mm diameter with soft-yellow tint (N)

Dial: approx. 1.750in diameter with soft-green tint (B)
approx. 45mm diameter with soft-yellow tint (O)

A practical solution for inspectors and machine operators who need to eliminate the potential for indicator misreadings. No matter how far out of tolerance a part may be, the needle of a one revolution indicator will always stay in the red, non-read zone - no passing zero again - no reading errors.

Long Range and Extra Long Range Indicators

For applications where extended measuring range is needed or spindle retraction is necessary.

Backs for ANSI / AGD Group 1-4, Single Revolution and Long Range Dial Indicators

Provides improved readability where other style indicators cannot be used.

Splashproof protection from coolant, oil, or other contaminants.
