WATER TESTING
Perfect Solutions For Testing Times Thanks to numerous innovations, the testing of water in pools and spas is now more sophisticated, accurate and convenient than ever. It’s a sector which has embraced the latest advances in technology whilst also still producing more lowtech, tried and tested methods too. The result is a wide range of products, some of which have revolutionised the process. With water testing always a high priority, we take a closer look at some of the available products By Jon Wadeson

rystal clear, clean and safe water is an essential and expected part of the wet leisure experience, but the last thing owners and operators of pools and spas want to do is spend an excessive amount of time and energy testing and monitoring their water, let alone doing it with equipment that isn’t pinpoint inaccurate. Fast, straightforward and accurate water testing products are therefore top of the list of many involved in ensuring the quality of wet leisure water – not just for safety reasons, but also to ensure equipment is operating within the correct environment too. If it isn’t, there’s often a heavy price to pay with new equipment being needed earlier than expected. The safety of anyone enjoying the water is of course at the top of every pool or spa owners’ list though, and with commercial facilities experiencing much higher bather loads than their domestic cousins, owners and users need to be able to trust that the water being used by bathers is safe and in the best possible condition. Considerable time and money has been spent on researching and developing more efficient and user-friendly testing systems, and that’s not surprising, as for commercial operators in particular, where there is the possibility of infection, only the latest products and best procedures are good enough. Down time as a result of poor procedures invariably leads to bad press, and this often spells disaster to a facility’s reputation, with guests then voting with their feet – a scenario to be avoided at all costs! Regardless of their size though, wet leisure facilities are always major investments for their owners and they, along with the water within them, need to be kept in the best possible condition. So having the correct products to test water conditions on an ongoing basis is a must

and here, we take a look at just some of the available testing solutions.
HANNA’S COMPLETE KIT FOR POOL, SPA AND HOT TUB WATER The HI-971044C from Hanna Instruments is a complete kit containing an advanced portable photometer for the measurement of pH, alkalinity, free chlorine and total chlorine, plus cyanuric acid in swimming pool, hot tub and spa water. At the heart of the kit is the HI-971044 photometer that has an innovative optical system that utilises a reference detector and narrow band interference filters to provide superior performance in accuracy and repeatability. With no warm up time needed before taking a measurement, it also shortens the time taken for water testing. The advanced optical system features: • An LED that generates very little heat
• An 8 nm narrowband interference filter that is accurate to +/- 1 nm and offers 25% increase in light efficiency • A reference detector that modulates the voltage to LED for consistent light output • A concave focusing lens that reduces errors from imperfections in the cuvette. This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step by step, in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different methods, reviewing GLP data, recalling the last 50 measurements and customising the meter to user preferences. HI-971044 is waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a protected battery compartment that holds three AA batteries. The compact design fits comfortably in the hand for use in the field or on a table for benchtop use. Users can select the use of powder reagents supplied in packets or the use of low cost liquid reagents supplied in a dropper bottle.
