Chemical analysis for swimming pools

The reliable testing routine to ensure healthy water in private swimming pools and hot whirlpools

POOLTESTER Chlorine-pH: allows simultaneous determination of free chlorine (either over the measuring range 0.1 - 3 mg/l or 0.5 - 6 mg/l) and pH value (6.8 - 8.2) using Lovibond® tablet reagents with long-term stability.

The disinfecting potential of the chlorine kills germs quickly and reliably, while its oxidation potential ensures degradation of organic pollutants.

POOLTESTER Bromine-pH: is used to measure the concentration of bromine (1– - 8 mg/l) and pH value (6.8 - 8.2) where, for example, bromine sticks are used as disinfecting agents.

POOLTESTER Active oxygen-pH: is used to measure active oxygen content (0 - 10 mg/l) and pH value (6.8 - 8.2).

POOLTESTER QAC-pH: is used to measure QAC content (25 - 150 mg / l) and pH value (6.8 - 8.2).

POOLTESTER Biguanide/Hydrogen Peroxide-pH: measures the pH value (6.8 - 8.2) and the concentration of biguanide (PHMB 10 - 100 mg / l), (various trade names are used for biguanide). A further water treatment agent with disinfection and oxidation potential is hydrogen peroxide, which is measured over the range 5 - 50 mg / l H2O2.

POOLTESTER Copper-pH: allows measurement of copper concentration (0.1 - 0.9 mg / l) and pH value (6.8 - 7.8). Copper is used as an algicide to prevent algae formation or to remove existing algae in water.


Chemical analysis with the MINIKIT®

Quick, simple tests for the analysis of boiler water, cooling water, drinking and industrial water. Using tablet reagents with long-term stability.

Advantages: easy operation and exact reagent dosing without any additional equipment, measurement accuracy even in difficult operating environments, unrestricted shipment and safe storage, foil-wrapped Lovibond® tablet reagents with a minimum guaranteed shelf life of 5 years, each kit contains sufficient reagents for an average 30 tests.

The methods

Tablet count method: the liquid titration solution and indicator are replaced by Lovibond® tablet reagents. A specific number of tablets is added to a defined sample volume until a chemically induced colour change takes place. The concentration of the parameter being measured is calculated from the number of tablets required. The measuring range can be expanded by varying the sample volume.

Speed test: is based on reverse titration. After adding a reagent tablet to a calibrated test tube, the water sample is added slowly until the colour of the solution changes (e.g. from red to blue). The user can then obtain the result from the liquid level.

Yes/No test: tells the user whether a specific ingredient is present in the water and/or if its concentration is higher or lower than a defined level.

Turbidity method: a two-section calibrated test tube is filled with the water sample and a reagent tablet added. The reagent creates a level of turbidity that is proportional to the concentration of the parameter being measured. The inner tube, which has a black dot on its base, is lowered until the dot is obscured by the turbidity. The result is read off from the water level in the inner tube.

Chemical analysis with the CHECKIT®Comparator

With continuous colour scale low cost - precise - reliable

Applications: Water Treatment (e.g. Drinking Water), Pools, Laboratory and Field Testing

The CHECKIT®Comparator is a compact, handy colorimetric unit which is suitable both for mobile and stationary analysis work.

Supplied with a generous number of different colour scales, it provides the basis for a comprehensive, easy-to-use colorimetric analysis system. The two cells are filled with the water sample and one is placed directly into the left-hand compartment of the comparator, where it acts as compensation (blank) for coloured or cloudy samples.

In the second cell, the reagents required for the analysis (tablets, powder or liquids) are mixed with the sample and this cell is then placed in the right-hand compartment of the comparator. The relevant CHECKIT®Disc is inserted in the comparator and turned until the colour standard matches the coloured water sample. The result can then be read in the large display window.

The diffuser plate on the rear of the comparator is used to provide compensation for ambient influences and unfavourable lighting conditions.

CHECKIT®Disc

Each CHECKIT®Disc contains a continuous colour scale which makes it possible to achieve an exact colour match between the colour standard and the sample. These CHECKIT®Discs are specially manufactured in selected materials to remain colour-stability over a long period and guarantee reliable, reproducible measurement results.

Instruction manuals explaining the various stages of analysis in simple, straightforward terms, are supplied with each CHECKIT®Disc.

BOD-Measurement

OxiDirect BOD-Measurement-System

  • Direct and Accurate BOD, 1-28 days measurements, Mercury-free
  • Direct sample selection
  • Accurate and direct display of BOD values in mg/l
  • User-friendly handling
  • User-selectable measuring period from 1 to 28 days (BOD5, BOD7, OECD...)
  • Automatic storage of BOD values
  • Measuring ranges from 0-40 mg/l to 0-4000 mg/l BOD / sample volume related
  • Automatic start function following temperature equalisation of the samples
  • Mercury-free, environmentally-friendly BOD determination
  • Inductive stirring system with automatic
  • re-centering of stirring rods
  • Interface RS 232

Respirometric methods provide direct measurement of the oxygen consumed by microorganisms from an air or oxygen-enriched environment in a closed vessel under conditions of constant temperature and agitation. Carbon dioxide produced metabolically by the bacteria is chemically bound by the potassium hydroxide solution contained in the seal cup in the bottle.

The result is a pressure drop in the system, which is directly proportional to the BOD value and is measured by the BOD sensor. The BOD level is then displayed directly in mg/l.

The BOD values are stored in the sensor memory and can be called up on the large-format display at any time without the need for time-consuming conversion using factors. This means that test series that end on a Sunday can be evaluated during the following week without any problem.

The measurement period is user-selectable between 1 and 28 days to suit the application. While short measurement periods are useful for scientific applications, standard BOD measurements typically extend over a period of 5 days – and manometric determination of OECD, for example, generally takes place over a period of 28 days.

Automatic start function: variations in sample temperature prior to testing result in pressure variations within the measuring system during the temperature equalisation period in the thermostatically controlled cabinet (if BOD measurement is to take place at 20°C, for example). Such variations would normally cause errors during manometric measurement. In order to prevent such errors, the Lovibond® OxiDirect® BOD meter is equipped with an automatic start feature: measurement does not commence until the temperature in the samples is the same as that in the thermostatically controlled cabinet. This rules out the possibility of temperature (and hence pressure) fluctuations that are not related to the manometric measurement.

The complete BOD measuring system: In addition to the BOD unit for measurement and storage of BOD levels, the OxiDirect® BOD measuring system includes sample bottles, measuring sensors, non-wearing inductive stirring system, overflow measuring flasks for metering of sample volumes, nitrification inhibitor and potassium hydroxide as an absorbent.
