We calibrate and repair a wide range of electrical test and measurement equipment so you can have confidence in the accuracy and safety of the devices you use every day.

We understand that the reliability of your test meter equipment is important to you and your customers.  Over time, the performance of your metering equipment can deteriorate. Regular calibration ensures test results remain accurate and the device is safe to use. So you know when servicing or repair is required, we'll send you a friendly reminder when your equipment is next due for checking.

From handheld multi-meters and power analysers to high voltage testers, we check the accuracy and safety of all makes commonly used by electricians and electrical companies in New Zealand. We are continually expanding the range of equipment we calibrate and if we can't calibrate your equipment ourselves, we are happy to arrange external calibration.

Our calibration laboratory is fully accredited by IANZ to the international standard NZS ISO/IEC 17025:2005. Our certification has been maintained continuously since 1995. We also offer non-endorsed calibration to traceable specifications, for devices not covered by the international standard.
