Indicator Gauge

S.G. Prittie manufactures indicator gauges using either digital or analogue indicators. The most common application for these gauges is to measure the depth of a hole or chamfer. These gauges are particularly suited to tight tolerances, we can supply indicators with 0.001mm resolution and setting masters to suit. Note flush pin gauges are also available if you have a tolerance greater than 0.2 mm. All of our gauges are made from hardened tool steel to ensure long life and are supplied with manufacturers certificate of conformance. (COC)

Why this product is used

Indicator gauges are a very quick way to accurately check the depth of a hole for conformance. Check the set point of the indicator gauge on the master, then apply to the part. The indicator will show a depth reading, compare the reading with the specification to find if the part is conforming.

  • Customisation

    Customisation is offered on most gauges. We can add a new feature to a standard gauge, manufacture a revised design based on a standard gauge, or design a new gauge to suit your application.

  • Support

    We offer design and technical support for all our gauges, as well as support for measurement and calibration inquiries. Contact us via phone or email.

  • Delivery

    We offer express or economy delivery and can send products to local, interstate and overseas locations. We’re also happy to use your own delivery supplier.

  • Manufacturing

    We are an Australian business located in Airport West Victoria. Quality is a priority and we have ISO 9001 and ISO 17025 management systems in place.

What are the advantages of an indicator gauge?

The gauge is purposely designed to suit a particular dimension. Measurements are very quick to perform and accuracy can be very high. Usually a setting master is used as a reference for setting the indicator. No universal tools like depth micrometers are required.

Is a flush pin gauge the same as an indicator gauge?

No, a flush pin gauge uses a ground step instead of an indicator to show the tolerance band. The step needs to be at least 0.2 mm deep to be useful.

Can a gauge be made to my own specification?

Yes, we can design indicator gauges to suit your products.

How often do I need to calibrate my gauge?

There is no fixed time, calibration frequency is based on how often the gauge is used and the conditions that the gauge is exposed to. Frequent use and abrasive materials will require more frequent calibration, low use in a clean environment will allow less frequent calibration. Usually the user determines the calibration frequency.
