The range includes simple block testers through to photometer-based digital systems. The newest addition is the MD100 PoolControl Range which comprises two models – MD100 3in1 for chlorine and pH, MD100 6in1 for chlorine, pH, bromine, total alkalinity and calcium hardness. Lovibond Tintometer has this year been running water testing training courses around the country throughout to step up the quality of training in water testing.
The courses, suitable for anyone involved in pool water testing, include: taking the sample; good practice in testing; what we test for and why; testing equipment and correct usage; an overview of balanced water and an on-hand, practical session where candidates can test samples of their own pool water.
All successful candidates will receive a Lovibond approved and signed Certificate of Completion. For a detailed agenda and list of dates and locations, contact

HANNA DIGITAL TECHNOLOGY 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 vital parameters needed to ensure clear and safe pool and spa water.

Advanced digital technology is packaged into this photometer, the Hanna HI-96725 which measures all three parameters quickly and accurately. This model 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 operational efficiency. It is ideal for routine pool maintenance and operates using a single button, produces reliable results in seconds testing for free and total chlorine, cyanuric acid and pH.
This Portable Pool Tester is part of a wider range of testing equipment and accessories manufactured by Hanna and sold in the UK. The Hanna Pocket meter is a favourite. Offering the same accuracy as a bench pH meter, it offers high precision testing in a portable pocket-sized format. Portable, waterproof and with a
rubberised keyboard, the dual level LCD display gives readings for both pH and temperature. What’s more, with one quick dip test, it does

use colour match systems are economic, consistent and enable reliable testing. Typically, the systems are colour-stable, made of non-fade glass and ensure consistent results over many years without the need for recalibration. The simple nature of the system means there is little to fail and kits are always ready to use. Moreover, there are over 400 different test discs commercially available to read an extensive list from alkalinity to zinc. However there are some disadvantages. The readings are, by their nature, subjective and can be affected by a number of external influences. Comparators should be used in natural daylight so additional lighting systems may be needed. They rely on an individual’s ability for colour matching – not everyone is competent or accurate (8% of males are said to suffer from some form of
colour vision deficiency). Finally, although readings can be recorded, they must be noted by hand. There is no ability to print or store the results electronically.
PHOTOMETERS
Photometers are electronic instruments designed to measure parameters via the colourmetric principle. The units give a direct, accurate digital reading of the test being carried out – clearly displayed on the screen. This removes any potential subjectivity being imposed on the reading. They are easy to use and can be operated in any lighting conditions. Most photometers can also be battery operated so still appropriate for in situ use.
Many photometers also enable the results to be transferred to either a printer or,
alternatively, to a PC where they can naturally be stored for review or historic reporting. This is beneficial to any facility where water quality might be subjected to audits. Being electronic, however, does mean the instruments do need to be well maintained, kept clean and regularly calibrated. Check Standards are now available to help verify the instrument’s calibration. Unfortunately, poorly maintained photometers will still give results – however meaningless they are. Care should therefore be taken to ensure they are serviced regularly. Whichever system you select, it is imperative that those carrying out the testing have the correct training, know how to use the equipment, understand the importance of water testing and remember the 3 Rs: Read – Record – React.
