Water-ID - PoolLab 1.0 Replacement Cuvette - POLsp-kv

Water-ID – PoolLab 1.0 Replacement Cuvette (POLsp-kv)

The genuine Water-ID replacement cuvette (POLsp-kv) is the official spare sample chamber for the PoolLab 1.0 photometer — the component through which all photometric pool water measurements are taken. Over time, scratches, staining, or chemical residue build-up can compromise optical clarity and skew readings, making timely cuvette replacement essential for reliable results. Supplied as a single unit direct from Water-i.d. GmbH, Germany, it restores your photometer to factory-standard measurement performance.

Compatibility

This cuvette is designed for the Water-ID PoolLab 1.0 photometer and is also confirmed compatible with the PoolLab 2.0. It fits via a practical bayonet-lock mechanism, allowing fast, tool-free swapping in the field. If you own both devices or are upgrading from a 1.0 to a 2.0, one spare cuvette covers both instruments.

Why Genuine Matters

The PoolLab 1.0 uses a triple-wavelength LED optical system to analyse up to 14 pool water parameters — including pH, free/combined/total chlorine, total alkalinity, cyanuric acid, calcium hardness, bromine, hydrogen peroxide, and more. Even minor optical imperfections in a third-party cuvette can introduce measurement error across all these parameters. A genuine Water-ID cuvette is manufactured to the exact optical tolerances required by the photometer’s calibration curves, ensuring the digital readings you rely on for dosing decisions remain accurate.

When and How to Replace

Replace the cuvette whenever you notice persistent cloudiness, deep scratches, or results that drift unexpectedly between tests. Always change the cuvette only when it is completely dry — never while wet. After fitting the new cuvette using the bayonet lock, a full recalibration of the photometer is required before resuming measurements. Clean the cuvette thoroughly after every use to maximise its service life and protect measurement accuracy.
