PoolLab 2.0 *New*

The PoolLab 2.0 is the perfect solution for professional water analysis of pools and spas.

The PoolLab 2.0 is the newest photometer from Water-ID, makers of the PrimeLab photometer. Water-ID brought their experience making high quality professional photometers to the consumer market with the PoolLab.

The PoolLab 2.0 is the perfect solution for professional water analysis of pools and spas. The fixed but exchangeable triple measurement-cuvette allows quick sampling by simply dipping the IP68 waterproof Pool LabⓇ into the water. THe device has 9 buttons to give quick access to the ZERO operation (only required 1 x per measurement batch) and to the 24 different pool water parameters.

It has a waterproof rating of IP68, so the whole device can be dipped into the water to collect the sample. The device has onboard storage of results and Bluetooth to connect to a phone or tablet. This allows you to save results digitally and optionally upload them to the cloud where they can be syncronised with other devices (computers, phones or tablets).

The eXact Strip Reagent Method

Now there is an alternative to powder pillows, powder packets, tablets, glass ampoules, and liquid systems: eXact Reagent Strips! By dipping a strip into a cell, the exact amount of reagent is released into the water causing a reaction. The reaction inside the water sample is measured by light inside the photometer giving the user fast and exact results.
