The color chart may also have numbers on it. Those numbers reveal how many minerals are in your water per gallon, per liter, or million units. Most times, you will see the terms GPM or PPM/mg/L used together. Our water test kits are available as . All-in-One Wat er Testing Kits, Water Test Kits for a single contaminant, Pool test kits or Digital Water Test Kits for a single & multiple tests: Find out which water test kit is right for you Legionella Water Tests

The colors show the presence of calcium and magnesium in your water. Calcium and magnesium are the minerals that make your water hard. Each color shows a different degree of water hardness. The customer shall cooperate with VWR in all matters relating to the services, provide all such access and information as is necessary and obtain any licences permissions and consents required before commencement of the services.Discs are usually more accurate than strips but can be more expensive. The discs run a series of tests at once. You drop water into each reagent-filled compartment. The reagent changes colors to indicate the presence of a contaminant. Digital Readers Soft water has 0-2 grains in every gallon. This is the same as 0-17.1 milligrams in every liter or parts in every million units. Water that is a bit hard Online analysers allow for continuous hardness monitoring. These instruments can activate alarms or control chemical feed pumps when the hardness concentration reaches a selected level. The main chemical used in water hardness test strips is acetic acid. The name of this acid is ethylene diamine tetra. I won’t get into the science of it. Since it is so long to pronounce, from now on, we will call this chemical EDTA.

While some hardness may be acceptable in certain water quality applications, others require zero hardness to prevent scaling and damage to equipment. Therefore, water softening by either precipitation or ion exchange is often necessary to remove hardness. To optimize these processes, it is sometimes important to monitor calcium and magnesium levels separately, along with total hardness. To reduce undesirable hardness, water must be softened. Softening methods typically fall into two main categories: Ion Exchange Softening Process This report tells you where your water came from and what it contains, including its concentration of calcium and magnesium hardness.Choose the right water testing kit for a water softener, water improvement & purification system, water cooler or a pool, spa or hot tub

Once you do the water hardness test, finding the correct methods to soften your water supply is easy. Any additional or special terms included by VWR in its written acceptance shall form part of the contract. The terms and conditions of the contract apply equally to the supply of both products and services except where application to one or the other is specified. With total hardness water quality test strips you are in control and can find out exactly where your calcium level is before it becomes a problem.

You may want to test your water after it goes through your home treatment system. Choose a pipe where the water passes through the water a softener. The pad is sensitive. Touching the testing pad may contaminate it or affect the chemicals in it. Any of these may lead to a false result. • Do not use a garden hose to take a water sample. If your glassware is prone to water stains, you will love these strips, which provide accurate results in less than a minute. This process exchanges cations causing hardness with non-hardness-causing cations, typically sodium, using either natural or synthetic ion-exchanging matrix, e.g. resin. For example, naturally occurring matrices include greensands and zeolites. Different ion-exchange resins (or matrices) possess varying properties. Synthetic materials tend to have a higher exchange capacity, so they are better for removing higher levels of hardness. Resins using hydrogen as the cation are commonly referred to as demineralizers and usually are comprised of both cation and anion-exchange resins to maintain neutral pH. For health reasons, it is important to note that sodium-based resin will increase the sodium levels in the treated water. This may also provide interference to some ULR hardness methods.
