Introduction
Product Definition
B27 Soft Water Hardness Reagent (Brand: Jubway/家贝) is a chemical reagent specifically designed for testing the hardness of water with low calcium and magnesium content. It is suitable for soft water systems such as RO purified water and boiler water. Through color reaction and titration, it allows rapid determination of whether the water hardness is within a safe range, helping users monitor the operating condition of water treatment equipment.
Product Features
- Designed for low-hardness water: the detection range covers 0.4~20 mg/L, providing higher accuracy for low-calcium and low-magnesium water samples such as soft water and RO water.
- Easy operation: the reagent kit is complete, and during titration according to the instructions, the endpoint can be judged by observing the color change, without the need for professional instruments.
- Cost-effective and durable: a single box can perform approximately 40 tests, making it suitable for routine periodic monitoring.
- Convenient storage: store at room temperature away from light, with a shelf life of up to 24 months.
- Practical specifications: contains 1 bottle of 10 ml reagent and 2 bottles of 30 ml reagent to meet multiple testing needs.

FAQ
Q: What is the detection range of the B27 Soft Water Hardness Reagent?
A: The detection range is 0.4~20 mg/L (as calcium carbonate), which is suitable for determining the hardness of water with low calcium and magnesium content.
Q: How many tests can one box of reagent perform?
A: Under standard operation, each box can be used for approximately 40 tests.
Q: What water samples is this reagent suitable for testing?
A: It is mainly suitable for low-calcium and low-magnesium soft water such as RO water and boiler water. It is not suitable for high-hardness raw water or wastewater.
Q: What is the shelf life of the reagent?
A: When stored at room temperature away from light, the shelf life is 24 months.
Q: How are the hardness test results determined?
A: The endpoint is determined by the color change of the reagent during titration, and the hardness value of the water sample is calculated from the number of drops consumed. For detailed instructions, please refer to the product manual.

- Soft water: water with low calcium and magnesium ion content, usually with hardness below a certain threshold.
- Hardness: the total concentration of calcium and magnesium ions in water, commonly expressed in mg/L (CaCO₃).
- RO water: purified water treated by a reverse osmosis membrane, which removes most dissolved salts.
- Boiler water: water circulated in a boiler system; its hardness must be strictly controlled to prevent scale formation.
- Titration: a method in which a reagent of known concentration is added dropwise until the reaction endpoint is reached, so as to calculate the concentration of the analyte.
