WEILAOK Water Hardness Measuring, Water Hardness Test, Water Hardness Measuring, German Grade Hardness (°dH) Quick and Easy Measurement for up to 200 Measurements, Titration Solution Water Hardness

• Precise and reliable: titration solution water hardness for precise measurement of total water hardness. A clear colour change indicator indicates the water quality and ensures the precise concentration of each drop of the test solution.
• Easy to use: measure water hardness. Add 5 ml of water sample to the measuring container and add the test solution drop by drop until the colour changes from red to blue. The number of drops added directly corresponds to the water hardness value (1 drop = 1°dH), so no complicated calculations are required. Even amateurs can easily determine the water hardness and quickly understand.
• Effective and efficient: the water hardness test large 15 ml bottle contains approx. 550 drops of test solution. Depending on the water hardness, it can be used much more frequently than comparable products: with a water hardness of 2 °dH, approx. 225 tests possible; even with a hardness of 10°dH, there are still approx. 55 tests - excellent value for money.
• Versatile: for water hardness tester testing of the limescale content of tap water, for analysis of drinking water quality, water softeners, water quality in aquariums and more. This product meets the diverse requirements for water quality monitoring for home and hobby users.
• Complete set: the hardness water measuring package contains all the necessary components: 1 bottle of hardness titration solution (15 ml), 1 special measuring container.

Product Name: Water Hardness Tester Keywords: water hardness tester Kit contains: 15ml water hardness tester + 15ml measuring cup Advantages: Quickly and accurately measures the total hardness of the water based on the number of drops and the colour change (from red to blue). So you can intuitively capture water quality, effectively monitor limescale deposits, protect the health of your aquarium and check the performance of your water softener. Instructions: Add 5 ml of water sample to the measuring container. Add the test solution drop by drop and shake evenly until colour changes from red to blue. The number of drops directly corresponds to the water hardness value (1 drop = 1°dH). Hardness conversion: The German definition of hardness is: 10 mg of calcium oxide per litre of water corresponds to 1 degree (°dH). 1 °DH = 10 mg/l (CaO). 1°DH = 17.86 mg/l (CaCO3). 1 °DH = 0.178 mmol/l (mmol/l). Soft water: 0-4°DH; Medium soft water: 4-8°DH; Medium hard water: 8-16°DH; Hard water: 16-30°DH; Extremely hard water: >30°DH Important Notes: 1. Avoid direct contact with skin and eyes. 2. Store in a cool and dry place, away from direct sunlight and high temperatures. 3. Keep out of reach of children and pets. Safety instructions: Keep away from fire and high temperatures. Keep away from children and pets. Avoid contact with skin and eyes.
