Precision Measurement: A Pro's Guide to Metering Accessories

A modern electrical or communications installation is all about accurate data—whether you're measuring kilowatt-hours for a solar system or managing delicate satellite frequencies for a commercial fit-out. Getting those readings and signals right requires high-quality, precision components.

At SCHNAP, our range of Metering Accessories is designed for just that. We provide the high-accuracy components that sparkies, solar techs, and switchboard builders need to deliver reliable, high-performance results on every job.

For Electrical & Solar Power Metering

Keep an accurate count of every watt with our professional power measurement tools.

  • Split-Core CTs (Current Transformers): The ultimate retrofit solution for energy monitoring and solar installations. A split-core CT is a clever clamp that clips around an existing mains cable without requiring you to disconnect the power. It safely and accurately measures the current flowing through the cable, feeding that data to a smart meter. It's the fastest and easiest way to add consumption monitoring to any switchboard.
  • DIN-Mount Transformers: The professional way to power your control circuits. Our DIN-mount transformers provide a safe, isolated, low-voltage supply for your meters, timers, and other control gear, all mounted neatly inside a switchboard.

For Satellite & RF Signal Management

Ensure a crystal-clear picture and reliable signal distribution in your AV and satellite setups.

  • LNB Units (Low-Noise Block Downconverters): The essential component that sits on the arm of every satellite dish. A high-quality LNB is the key to capturing a strong, clean signal from the satellite, which is the first step to a perfect picture.
  • Diplexers: The smart device that simplifies your cable runs. A diplexer allows you to combine two different signals (like a standard Free-to-Air TV antenna signal and a satellite signal) onto a single coaxial cable. A second diplexer at the other end splits them back out again.

Trusted Brands for Accurate Measurement

When precision matters, you need to trust your components. We stock a huge range of high-performance metering accessories from the most respected brands in the industry, including Legrand and Matchmaster. Every product is engineered for fast, reliable installs and is compliant with Australian standards.

Why Specialists Choose SCHNAP

For the precision components that make your advanced systems work flawlessly.

  • A complete range of CTs, transformers, LNBs, and diplexers.
  • Trusted, industry-leading brands known for accuracy and reliability.
  • Check live stock levels across Australia.
  • Fast delivery and competitive trade pricing for professionals.

For all the essential Metering Accessories you need for your next technical installation, trust SCHNAP to have the right gear in stock.
