Product Background: Calcium and Magnesium ions are the major contents that define water hardness. From environment and health perspectives, excessive hard water is not good for drinking and washing. In addition, water hardness is an important indicator of industrial water quality and hardness change test of softened water, on regular basis, are needed in various industries, such as boiler and dyeing industries. Hence, developing a new Calcium and Magnesium ion test agent enabling fast and simplified determination is of great importance for water quality testing and assessment. The researchers of Ningbo Thaile Chemical Technology Co., Ltd have after years of in-depth study, successfully developed a new Calcium and Magnesium ion test agent, under the brand of "Thaile". The invention of this agent can achieve better and reliable results with greatly simplified operation and lowered testing costs.
Product Theory: Use a specific high-sensitivity reagents, it can generate chemical reaction with Calcium and Magnesium ions.
Product Use: Rapid qualitative test of calcium and magnesium ions in water. Usually it used in on-site rapid testing of living water, aquaculture, environmental protection, industrial water etc. 
Product Features: Accurate, easy to handle, inexpensive, easy to carry.
Method of Using:
1.Wash the colorimetric tube twice with water sample. Then, measure and take certain amount of water using the colorimetric tube. Adjust the level to the graduation mark of 15ml using a plastic dropper.
2.Spray the agent, in at least 3-4 times, into the colorimetric tube and shake gently until it dissolves sufficiently.
3.Allow dozens seconds of resting before observation. The whiter the solution appears, the water contains more Calcium and Magnesium ions, contrariwise less. When it is crystal clear, there is no Calcium and Magnesium ion content. If the vial gets blocked up during the spray, shake it up and down, or use a needle to unblock it. When it s hard to spray out the product due to agglomeration, just open the vial and pour out a little. This will not affect the result of determination as long as the agent well dissolved by shaking during the usage.
Cautions:
1.This product is slightly irritating and aggressive, avoid inhaling. In case of body contacts, rinse with water.
2. After use, please tighten the cap to avoid ineffectiveness.
3. Try to compare the colors in bright light.
