Water-ID - Nitrate Test Shaker 25 ml for PoolLab 2.0 - FW25-shaker

Water-ID – Nitrate Test Shaker 25 ml for PoolLab 2.0

The Water-ID 25 ml Nitrate Test Shaker (FW25-shaker) is a dedicated accessory for the PoolLab 2.0 photometer, required to carry out the nitrate measurement procedure correctly. Without it, the nitrate reagent cannot be properly mixed with the water sample, making accurate photometric readings impossible. It is a mandatory addition for any PoolLab 2.0 user who needs to monitor nitrate levels in pool or spa water.

Why Nitrate Testing Matters

Elevated nitrate levels in pool water are a common consequence of organic contamination — from bather load, fertiliser runoff, or breakdown of nitrogen-containing compounds. High nitrate promotes algae growth, reduces the effectiveness of disinfectants, and can signal deteriorating water quality. Regular testing helps pool operators and technicians catch imbalances early and take corrective action before water quality suffers.

Compatibility

This shaker is designed exclusively for use with the Water-ID PoolLab 2.0 photometer and its corresponding nitrate reagents. It is not compatible with the older PoolLab 1.0. If you own a PoolLab 2.0 and test for nitrate, this accessory is a required part of the workflow — it cannot be substituted with a generic vessel, as the 25 ml volume and mixing design are matched to the PoolLab 2.0 nitrate test protocol.

How to Use

Fill the shaker to the 25 ml mark with your pool water sample, add the nitrate reagent as directed in the PoolLab 2.0 user manual, seal and shake thoroughly to ensure complete dissolution and reaction, then transfer the prepared sample to the photometer cuvette for measurement. Following the precise volume and shaking steps specified in the manual is essential for reliable, repeatable results.
