Peace of Mind

Warranty That Means It

Every GreyLink device ships with a comprehensive hardware warranty. And because every device is custom-built for your specific application, you define what normal operating conditions look like — not us.

Standard

5-Year Warranty

All GreyLink devices are covered for 5 years under standard use. Because your device is built for your exact application, you agree with us upfront what normal operating conditions are — so the warranty is always fair and clear.

  • You define normal operating conditions at commissioning
  • Repair or full replacement at no charge
  • Applies to every GreyLink device, no exclusions
Premium

Warranty Unlimited

The ultimate peace of mind. Your GreyLink device is covered forever, under the operating conditions you specify. Even many years down the line — your device will be replaced. No expiry. No fine print.

  • You define the operating conditions — we honour them for life
  • Device replaced even years after purchase
  • No time limit — ever

You write the rules.

Every GreyLink device is custom-built for your specific application — whether that's a pump running 18 hours a day, a sensor in a -20 °C cold room, or a meter strapped to a high-vibration motor. At commissioning, we document your exact operating conditions together. Those agreed conditions become your warranty baseline, so there's never ambiguity about what's covered.
