All test are NATA tracable, and three separate tests are performed on your guage to ensure "fit for use"

Repair Services

With our experience of calibration and repairs, we find that gauges have a reliable life of typically anywhere between 5 years and 25 years. This depends on the type of gauge, and their use.

The Asian made gauges tend to have a shorter life. Good quality U.S. gauges are more reliable long term, and generally have a longer life.

Should your gauge need maintenance or repair, we charge a minimum $110 + GST to carry out any work on it.

Extra costs may apply if further work, or parts, are required.
