WATER TESTING
Taking The Guesswork Out Of Water Testing
IN TODAY’S HIGH TECH INDUSTRY, THERE ARE NO EXCUSES FOR NOT REGULARLY, CORRECTLY AND PRECISELY TESTING WATER QUALITY. CURRENT TESTING PRODUCTS ARE SOPHISTICATED, ACCURATE AND AVAILABLE FOR EVERY TYPE OF POOL SCENARIO. WHILE MANUFACTURERS CONTINUE TO DEVELOPIMPROVED PRODUCTS, THE KEY TO CARRYING OUR CORRECT TESTING IS KNOWLEDGE, TRAINING, AN UNDERSTANDING OF THE AVAILABLE PRODUCTS COMBINED WITH REACTING TO SITUATIONS THAT ARISE By Jon Wadeson
W
hen it comes to testing water, there is a mantra which those who do the testing would do well to remember. It’s read,
record and react – a simple summary of what is necessary, regardless of the product you are using or the water testing circumstances. Of course there are a number of factors that can hinder a tester from getting a good reading but as technology continues to provide further options for manufacturers to refine and improve their testing products, so the process becomes easier, more accurate and more likely to override any complications. It’s fair to say that there is no such thing as the perfect water testing system or product. It is just that some are more appropriate to what accuracy you are looking for, what you need to measure, whether the results need to be recorded and what budget you have to buy the product in the first place!
There is still a suspicion that some service professionals remain hesitant to use the latest products, perhaps because they don’t understand how these testing systems work, but modern products and systems really do
make the task of testing much easier than ever before and so there is no real excuse for not utilising the latest technology to make pool water as safe as possible. If anyone doubted the importance of proper testing, then it should be noted that cases of cryptosporidium are still regularly reported and it’s presence can spell disaster for a public pool in particular. In Wales last year, a swimming pool at The Newport Centre was forced to close for six weeks following an outbreak. In addition to the thousands of pounds it cost to drain, clean and re-grout the pool, plus make changes to the pool’s filters and more, perhaps the bigger cost is that consumer confidence in pool facilities is reduced.
One view is that the public should lead the way in making sure pool water is tested properly and demand to see audits of testing at their local pool.
The pH in a swimming pool is the single most important parameter, so to test it accurately is a priority. Testing methods on
the market vary from test strips and phenol red tablets to digital photometers and pH meters. Of these a pH meter is acknowledged to be the most accurate, fast and easy to use method. It uses no reagent but gives an instant digital readout across the full pH scale. Traditionally colour comparison systems, such as the Lovibond 2000+, were used to give accurate and reliable testing even in this more high-tech environment.
The ambition behind the swimming pool test kits has been to provide a quality of test results normally associated with laboratory analysis by trained technicians and a number of companies continue to invest in their products in an effort to meet that objective. Regardless of the systems and products now available, whether it is a tablet, strip or a digital option, the right product is out there in the market to suit all needs and the benefit is that all the testing products on the market are designed to eliminate the ‘guesswork’ as to what state the pool water might be in.
DIGITAL TECHNOLOGY FROM HANNA OFFERS FAST, ACCURATE RESULTS
The look and smell of the water in a pool can tell you a lot about its quality but the key to efficient pool maintenance is to ensure the correct levels of chlorine, cyanuric acid and pH levels. The Portable Pool Tester from Hanna Instruments measures all the parameters.
Advanced digital technology is packaged into the photometer, the Hanna HI-96725, which measures all three parameters quickly and accurately.

It comes complete with Hanna’s calibration check facility allowing the user to verify and calibrate the meter on-site. By removing the need to send the instrument back to the laboratory for calibration, Hanna has lowered the operational life costs associated with the Pool Tester and improved its efficiency. It is ideal for routine pool maintenance and operates using a single button and produces reliable results in seconds.
