Frequently Asked Questions — Outside Micrometers

If your operators need fast, error-free readings and you record measurements digitally, choose digital (3109 or 3101 series). If you prefer proven mechanical reliability with no battery dependency and your machinists can read a thimble scale, the analog 3203 series is the best value. Many Indian workshops keep both — digital for QC lab use and analog on the shopfloor. Shri Narayan Machinery LLP in Noida stocks both types.
