Accusize 0-1ft by 0.001ft Dial Indicator P900-S102 - Precision Dial

Our review of the Accusize 0-1' by 0.001' Dial Indicator P900-S102 finds it best suited for machine shops and inspection benches where repeatable, fine-resolution readings are required. The single biggest reason to buy is its consistent 0.001' resolution, which makes small-run measurement and setup tasks noticeably easier than with coarse indicators. Built to AGD 2 standards and equipped with a lug back mount, this indicator is practical for routine dimensional checks where straightforward zeroing and a durable contact point matter.

Key Features

• AGD 2 Standard Compliance: Ensures the indicator follows a widely used specification so it will be compatible with common inspection setups and mounts.
• Flexible Lug Back Mounting: The lug back with a 1/4' hole allows secure, repeatable installation on fixtures or magnetic bases for varied workshop tasks.
• Simple Zero Adjustment: The rotational bezel with clamp makes it quick to set and lock a reference point when performing comparative measurements.
• Hardened Contact Point: The interchangeable hardened contact tip adds wear resistance and extends functional life under normal use.
• Precise Measurement Range: The 0-1' range at 0.001' increments gives the fine granularity needed for alignment, runout, and small feature inspection.

Who It's For

This indicator is aimed at shop technicians, maintenance engineers, and hobbyists who need a compact, AGD 2 compatible dial indicator for fixture setup, runout checks, and comparative gauging. Its 0.001' resolution and lug back make it a practical choice for bench work and portable inspection with magnetic or clamp-style bases.

Users who require extreme heavy-duty field use or extended high-impact cycles should consider a more robust industrial-grade model, as some customers reported durability and fit issues after heavy daily use. For occasional bench checks and precision alignment, this unit is a solid, cost-effective option.

Pros & Cons

Pros

• Accurate 0.001' resolution for precise dimensional work and repeatable measurements.
• AGD 2 compliance provides broad compatibility with standard indicator mounts and fixtures.
• Lug back mounting and rotational bezel give flexible installation and easy zeroing on the fly.
• Interchangeable hardened contact point improves longevity under normal inspection conditions.

Cons

• Some users report mixed feedback about magnet strength and long-term durability, so heavy daily impact use may reveal weaknesses.

Frequently Asked Questions

Is this indicator compatible with standard mounts?
Yes, it is built to AGD 2 standards and uses a lug back with a 1/4' hole for common mounting options.

Can the contact point be replaced?
Yes, the unit includes an interchangeable hardened contact point to replace worn tips.

Is the magnet strong enough for overhead mounting?
Feedback is mixed on magnetic hold strength, so test mounting stability for critical overhead uses before relying on it long-term.
