SIGNIFICANCE OF POOL AND SPA TESTING A major family leisure pursuit is the enjoyment of Swimming Pool and Spa facilities world-wide. A basic necessity of Pool water treatment, to ensure such enjoyment, is to maintain the water in a safe and pleasant condition for the bathers. In order to achieve such an objective, swimming pool water requires testing on daily, and sometimes hourly bases for disinfection residuals and pH.
THE WATER BALANCE AND LANGELIER INDEX (LI) The pool water characteristics need to be maintained in a balanced condition to avoid system failure. Measuring the water balance is extremely important to predict if the water is corrosive, scaling or balanced. A saturation index developed by Dr. Wilfred Langelier is widely used to predict the balance of swimming pool waters. It is an estimation of the solutions ability to dissolve or precipitate calcium carbonate deposits.
pH The pH of the water is an important factor since at lower pH the corrosion rate increases. If the alkalinity values are sufficiently high it will not be difficult to control the pH. Most pools managers do prefer to keep the pH between 7.2 and 7.4, that does ensure low corrosion rates and a sufficient activity of chlorine. Langelier Index (LI) The Langelier Index is a powerful tool to calculate the water balance, and to predict corrosion or scaling problems.

FUNCTIONAL DESCRIPTION INSTRUMENT DESCRIPTION 1) 2) 3) 4) 5) 6) 7) 8) Open Cuvette Lid Indexing mark Cuvette point Liquid Crystal Display (LCD) Splash proof keypad ON/OFF power switch Power input connector USB connector 10
KEYPAD DESCRIPTION The keypad contains 8 direct keys and 3 functional keys with the following functions: Press to perform the function displayed above it on the LCD. ESC Press to exit the current screen. Press to access the select method menu. Press to move up in a menu or a help screen, to increment a set value, to access second level functions. Press to move down in a menu or a help screen, to decrement a set value, to access second level functions. Press to log the current reading.
(c) take out the syringe and clean the outside of the syringe tip. Be sure that no drops are hanging on the tip of the syringe, if so eliminate them. Then, keeping the syringe in vertical position above the cuvette, push the plunger down into the syringe until the lower edge of the seal is exactly on the 0.5 mL mark. Now the exact amount of 0.5 mL has been added to the cuvette, even if the tip still contains some solution.
USING CUVETTES • Proper mixing is very important for reproducibility of the measurements. The right way of mixing a cuvette is specified for each method in the related chapter. (a) invert the cuvette a couple of times or for a specified time: hold the cuvette in the vertical position. Turn the cuvette upside-down and wait for all of the solution to flow to the cap end, then return the cuvette to the upright vertical position and wait for all of the solution to flow to the cuvette bottom.
• In order to avoid reagent leaking and to obtain more accurate measurements, close the cuvette first with the supplied HDPE plastic stopper and then the black cap. • Each time the cuvette is used, the cap must be tightened to the same degree. • Whenever the cuvette is placed into the measurement cell, it must be dry outside, and free of fingerprints, oil or dirt. Wipe it thoroughly with HI 731318 or a lint-free cloth prior to insertion.
OPERATIONAL GUIDE POWER CONNECTION AND BATTERY MANAGEMENT The meter can be powered from an AC/DC adapter (included) or from the built-in rechargeable battery. Note: Always turn the meter off before unplugging it to ensure no data is lost. When the meter switches ON, it verifies if the power supply adapter is connected.
• After the desired method is selected, follow the measurement described in the related section. • Before performing a test you should read all the instructions carefully. DATA MANAGEMENT The instrument features a data log function to help you keep track of all your analysis. The data log can hold 200 individual measurements. Storing, viewing and deleting the data is possible using the LOG and RCL keys.. Storing data: You can store only a valid measurement.
