GENERAL DESCRIPTION C 99 & C 200 Series is a line of 17 different bench, microprocessorbased photometers to measure more than 50 different parameters in water and wastewater.
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.
between the hypochlorous acid (HOCl) and the hypochlorite ions (OCl-). Although both forms are considered free chlorine, it is the hypochlorous acid that provides the strongest disinfecting and oxidising characteristic of chlorine solutions. The amount of hypochlorous acid in chlorinated water dependends upon the pH value of the solution. Changes in pH value will effect the HOCl equilibrium in relation to the hydrogen and hypochlorite ion.
frequently large amounts of pool water. In general its application is found just before water passes through the filter units. Its sanitizing power is not pH related. Mainly because of its strong oxidizing power the return water may contain only trace concentrations of ozone. It has to be mentioned that ozone is very unstable and there is anyway the need for low-level chlorination to ensure sanitizing throughout the whole pool.
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. Theoretically, a LI of zero indicates perfect water condition for swimming pools.

PRINCIPLE OF OPERATION Absorption of Light is a typical phenomenon of interaction between electromagnetic radiation and matter. When a light beam crosses a substance, some of the radiation may be absorbed by atoms, molecules or crystal lattices.
A microprocessor controlled special tungsten lamp emits radiation which is first optically conditioned and beamed to the sample contained in the cuvet. The optical path is fixed by the diameter of the cuvet. Then the light is spectrally filtered to a narrow spectral bandwidth, to obtain a light beam of intensity Io or I. The photoelectric cell collects the radiation I that is not absorbed by the sample and converts it into an electric current, producing a potential in the mV range.

GUIDE TO DISPLAY CODES Note: The secondary LCD below shows a generic "P– –", whereas the meter will indicate the exact program number (e.g. in C 216, "P1" for Alkalinity). This indicates that the meter is in a ready state and zeroing can be performed. Sampling in progress. This flashing prompt appears each time the meter is performing a measurement. The microprocessor is adjusting the light level, indicated by a scrolling "SIP".
The lamp is not working properly. Contact your dealer or the nearest Hanna Customer Service Center. The lamp is not working properly. Contact your dealer or the nearest Hanna Customer Service Center. This indicates that the meter has lost its configuration. Contact your dealer or the nearest Hanna Customer Service Center. ERROR MESSAGES a) on zero reading: This indicates that the zeroing procedure failed due to a low signal-to-noise ratio. In this case press ZERO again.
A zero reading was not taken. Follow the instruction described in the measurement procedures for zeroing the meter. Under range. A blinking "0.00" indicates that the sample absorbs less light than the zero reference. Check the procedure and make sure that you use the same cuvet for reference (zero) and measurement. 1) A flashing value of the maximum concentration indicates an over range condition. The concentration of the sample is beyond the programmed range: dilute the sample and rerun the test.
TIPS FOR AN ACCURATE MEASUREMENT The instructions listed below should be carefully followed during testing to ensure best accuracy. • Color or suspended matter in large amounts may cause interference, therefore, these should be removed by treatment with active carbon and by prior filtration. • For a correct filling of the cuvet: the liquid in the cuvet forms a convexity on the top; the bottom of this convexity must be at the same level of the 10 mL mark.
• In order to avoid reagent leaking and to obtain more accurate measurements, it is recommended to close the cuvet first with the supplied HDPE plastic stopper and then with the black cap. • Each time the cuvet is used, the cap must be tightened to the same degree. • Whenever the cuvet is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil or dirt.
