Overview

If you’ve received a new Gecko Waterlab probe or need to replace an existing one, you can easily do it through the Gecko App. The app will guide you step-by-step through the setup process to connect and calibrate your new probe.

Step-by-step instructions

  3. Go to Settings → Devices
    From the list, select Settings, then tap Devices.

    💡 Tip: Make sure your new probe is connected securely to the in.touch 3+ CO module and is submerged in water when prompted.

    Once the app confirms successful detection, the new probe’s serial number will appear in the Waterlab section under Probe.
