 Hardness | 0.0 - 500.0 mg/l (ppm) | reagent for measurements - Total hardness. The shelf life of liquid reagents is 6 months.

Basically dissolved salts belonging to the alkaline earth elements calcium and magnesium are found in non-distilled water. In rare cases, strontium and barium can also be found. These combine with carbonate ions to form water- insoluble compounds (calcium). Through the total hardness measurement, the potential danger of calcium precipitation is measured as the required carbonate ions form from hydrogen carbonate ions when water heats up or when there are pH values that are greater than 8.2 (comp. Alkalinity). When measuring calcium hardness (SVZ1300 tablet process), only the part of the dissolved calcium in water is measured. The amount of magnesium dissolved in water is determined from the difference between the measurement and the total hardness.

    The following parameters can be tested in salty water


    Parameter Fresh water Saltwater Seawater
    Active oxygen  
    Chlorine dioxide  
    Cyanuric acid  
    Total hardness    
    Calcium hardness  
    pH  *  
    Hydrogen peroxide


    * 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.

    In summary, a PoolWaterLAB photometer can be a cost-effective, convenient, and easy-to-use tool for maintaining your home pool. It provides accurate measurements of chemical levels in your pool water, helping you to prevent problems and keep your pool water clean and healthy.
