Sinclair International · 3033111N
Show deviations of 0.001 inch on the dial
The analog Sinclair dial indicator is designed as a robust working indicator for compatible measuring setups at the reloading bench. Its scale division is 0.001 inch – equivalent to 0.0254 mm – making it suitable for comparative checks of small displacement changes.


Why choose this dial indicator

direct analog display without battery or menu navigation
scale division of 0.001 inch for easily readable comparative measurements
described by Sinclair as a proven indicator for their own measuring tools
useful for repeatable test procedures with stable mounting



Check before buying

measuring stand, holder, or Sinclair measuring device are not included in this single item
mounting, clamping dimension, and required measuring travel must fit the existing setup
0.001 inch refers to the scale division, not automatically a guaranteed system accuracy
measuring range, calibration certificate, and metric display are not specified



What is it intended for?
A dial indicator records relative displacement changes: The contact point rests on the test point, the workpiece is moved or rotated for inspection, and the pointer deflection shows the deviation. In a suitable Sinclair measuring tool, this can help with runout, concentricity, or comparative adjustment checks. The actual dimension being checked is always determined by the measuring setup – not the dial indicator alone.
The display does not replace a complete measuring stand or a calibrated inspection workstation. For release limits and evaluation of measurement results, the specifications of the respective tool and your own documented inspection routine apply.


Works well if …

you are looking for an analog 0.001-inch dial indicator for a proven compatible Sinclair setup,
you want to clearly compare maximum and minimum values when rotating a workpiece,
you have a stable holder and can reproducibly zero it,
you consciously work in inches or can interpret 0.001 inch as 0.0254 mm.



Choose differently if …

you need a digital display or direct metric reading,
you expect a complete runout tester including base, rollers, and holder,
your existing setup requires different mounting or measuring travel data,
you need a certified measuring instrument with documented calibration.



Measure cleanly: practical tips

Secure the dial indicator play-free and torsion-resistant in the compatible holder.
Align the contact point as perpendicular as possible to the measuring path and only lightly preload.
Clean test point and contact surfaces
n; insert the workpiece without lateral pressure.
Zero the dial at the defined reference point.
Move or rotate the workpiece slowly and evenly; note the highest and lowest values.
Repeat the measurement after re-clamping to detect setup errors and outliers.

Avoid shocks, side load on the probe tip, and excessive preload. Before each use, check the return, pointer movement, and secure fit.


Scope of delivery

1 × Sinclair International analog dial indicator
Version with 0.001-inch scale division

Dial stand, concentricity tester, Instant Indicator, mounting parts, and workpieces are not included as part of this single item.


Buying advice in one sentence
Get this dial indicator if your existing Sinclair or workshop measuring system explicitly supports a matching analog 0.001-inch indicator; don’t buy it solely based on the scale division without matching the holder, measuring range, and desired testing method.


Classification for the reloading bench
The benefit comes from the complete measuring setup: stable mounting, clearly defined test point, and even movement are more important than as many decimal places as possible. You can find more freely available measuring and control aids in the Reloading Accessories section.
Frequently asked questions
Is 0.001 inch the accuracy of the dial indicator? The specification describes the scale division or reading increment. A guaranteed total accuracy of the complete measuring setup cannot be derived from this alone.
How much is 0.001 inch in millimeters? 0.001 inch equals 0.0254 mm.
Is a dial stand included? No. The single dial indicator is offered; a compatible holder or a complete measuring device is additionally required.
Can I measure cartridge runout with it? Yes, if the indicator is correctly mounted in a suitable, compatible runout or concentricity tester. Alone, it does not form a complete testing device.
Does the dial indicator have a metric display? The offered version is marked with 0.001 inch. A separate metric scale is not included.
Is a calibration certificate included? A calibration certificate is not specified for this item. For documentation-required tests, this should be clarified separately before purchase.
Why must compatibility be checked? Dial indicators differ in mounting, measuring range, and installation situation. Only a mechanically fitting and rigidly mounted indicator provides usable results in the existing setup.
