 Chlorine Free | 0.0 - 8.0 mg/l (ppm) | reagent for measurements - DPD N° 3. Shelf life tablet reagents 2 years. ( TbsPD350 )

Chlorine (in the form of sodium hypochlorite, calcium hypochlorite, chlorine gas, chlorinated isocyanurates,...) has become the leading disinfectant for swimming and bathing pool water worldwide. When measuring the chlorine concentration present in the water, a distinction is made between 3 partial values according to DIN EN 7393. 1 Free chlorine: Chlorine present as hypochlorous acid, hypochlorite ion or as dissolved elemental chlorine. 2. Combined chlorine: Proportion of total chlorine present in the form of chloramines and all chlorinated derivatives of organic nitrogen compounds. 3. Total chlorine: Sum of the former two forms. While free chlorine is immediately available for disinfection action, the disinfection potential of combined chlorine is severely limited. The chloramines are responsible for the typical indoor pool odor and the irritation of human mucous membranes, resulting in reddened eyes. A representative of this class of substances is nitrogen trichloride, which is already perceived by humans at a concentration of 0.02 mg/l. Free chlorine is measured according to the DPD N° 1 method. The indicator chemical N,N-diethyl-p-phenylenediamine sulfate (DPD) is oxidized by the chlorine and turns red. The more intense the discoloration, the more chlorine is present in the water. The chlorine concentration can now be determined by photometric measurement or optical comparison with a color scale. If a DPD N° 3 tablet is now added to this sample, the bound chlorine is also displayed. The measured value therefore now corresponds to the total chlorine concentration. The concentration of combined chlorine corresponds to the difference between total chlorine and free chlorine. Since even the smallest traces of the effective chemical of the DPD N° 3 tablets cause combined chlorine to become effective in the measurement, it is essential to ensure that the measuring device is cleaned extremely carefully before the next DPD N° 1 measurement in order to avoid a measurement error. The use of two different measuring vessels (one generally for the measurement of free and one generally for the measurement of total chlorine values) would be recommended.

* Special case pH measurement

Depending on the salt content of your sample, the measurement result must be corrected according to the following scheme:

1 molar = -0,21 pH
2 molar = -0,26 pH
3 molar = -0,29 pH
where: 1 mol salt (NaCl) = 5.8 % = 58.4 g/l

Pools with salt electrolysis are not affected.
In salt electrolysis, a maximum of 7 g/l salt is used, far less than 1 mol (58.4 g).

Why should I buy a PoolWaterLAB photometer to maintain my pool at home?

A PoolWaterLAB photometer is a device that measures the levels of various chemicals in your pool water, such as chlorine, pH, alkalinity, and hardness. Here are some reasons why you might consider buying a PoolWaterLAB photometer to maintain your home pool:

1. Accurate Measurements: A PoolWaterLAB photometer provides accurate measurements of the chemical levels in your pool water. This helps you to adjust the chemicals in your pool precisely and avoid over or under-dosing, which can lead to problems such as algae growth, cloudy water, and skin irritation.

2. Cost-Effective: Regular testing of your pool water is essential for maintaining healthy water conditions. Buying a PoolWaterLAB photometer may be more cost-effective than continually purchasing test strips or sending water samples to a lab for analysis.

3. Convenience: With a PoolWaterLAB photometer, you can test your pool water at home, at any time you want. This can be more convenient than traveling to a pool supply store or waiting for lab results.

4. Easy to Use: Most PoolWaterLAB photometers are easy to use and come with detailed instructions. You don't need to be a chemist to understand how to use the device, and most models provide digital readings that are easy to interpret.

5. Preventative Maintenance: Maintaining proper chemical levels in your pool can help prevent problems such as algae growth, cloudy water, and equipment damage. By using a PoolWaterLAB photometer to test your water regularly, you can catch any issues early and address them before they become more severe.
