Replacement multiparameter electrode for the Gecko Waterlab monitoring system. Designed to sit in the Waterlab chamber and connect to the in.touch 3+ CO module for continuous pH/ORP/temperature monitoring. Robust build, serviceable in situ, and engineered for low-turbulence flow inside the chamber.

What it does

• Measures water chemistry (pH, ORP and temperature) inside the controlled-flow chamber.

Compatibility (quick checks)

• Fits the Gecko Waterlab chamber.
• Requires in.touch 3+ (CO module with water monitoring board); not supported on in.touch 2 or in.touch 3.
• Works with in.yt / in.ye / in.yj packs (2012+).

Install & safety

• Power down the spa pack before handling sensors and opening the chamber.
• Lubricate O-rings with silicone grease; hand-tighten only.
• Rinse and calibrate per Waterlab instructions in the Gecko app.
• Keep the sensing end wet in suitable storage solution; never store in deionised water.

• Required module: in.touch 3+ (CO module with water monitoring board). Probe connects to the CO-port short cable.
• Supported packs: in.yt / in.ye / in.yj, manufacture year 2012 or newer.
• Not supported: in.touch 2 and in.touch 3.

1. Insert probe into Waterlab chamber and secure per orientation guidance (system within ±5° of vertical).
2. Connect to the CO module's short cable; verify LED status (blinking blue = normal, full red = no probe, full yellow = probe not yet identified).
3. After startup, allow ~30 minutes for readings to stabilize once flow is established.
4. Calibrate using Gecko app when prompted (typ. once over lifetime, ~2 years).
5. For cleaning, follow pH/ORP electrode guidance; recondition and recalibrate after cleaning.
6. Winterization: store wet in suitable solution; never dry; never in DI water.
