LaMotte WaterLink 3-Way Chlorine/Bromine/pH Spin Disk, 50 Pack, 4334-H

LaMotte 4334-H is the WaterLink 3-Way spin disk, sold 50 to a pack. Each disk runs chlorine, bromine and pH from a single water sample.

How the disk works

The reagents are sealed into the disk at the factory. The sample goes into the disk, the analyzer spins it, and each test chamber reads on its own. Nothing is counted out by hand and nothing is matched against a color block by eye, which is why spin testing is what most retail counters and service routes moved to.

Picking the right disk

The LaMotte spin range is split by which tests a disk carries, so the part number matters more than the name. This one, 4334-H, covers chlorine, bromine and pH. If you also want alkalinity in the same spin, that is a different LaMotte disk.
