Proper pool-shop water testing can at times take longer than customers are willing to wait. Testing with a conventional photometer, for example, can take up to 10 minutes if done properly, and wet chemistry labs take even longer.
The alternative has been to use test strip readers, which take around a minute to do six tests. But by their manufacturers' own admissions test strips can return readings. LaMotte in the US has developed a radically different photometer that combines the speed of a strip reader with the accuracy of a conventional photometer. The new photometer, WaterLink Spin, performs 10 tests - free and total chlorine, pH, alkalinity, hardness, cyanuric acid, copper, iron, bromine and borate - simultaneously in 60 seconds.
Only three steps are needed to perform the full suite of 10 tests. The first step is to syringe 3ml of water into a reagent disc. The second step is to insert the disc into the photometer light chamber. And the final step is to click the start button. According to Terry van Heerden, managing director of Vendart Pty Ltd, LaMotte's exclusive distributor in Australia and New Zealand, "WaterLink Spin will change the way pool shop managers approach the problem of water testing in their shops".
WaterLink Spin is supplied together with LaMotte's DataMate water testing software. DataMate has been upgraded to a new version 10.0, which includes an application to enable it to operate with WaterLink Spin and an improved user interface.
