ZIMEX |New AQUADUR TH 400 water hardness test strips for clearer readings
Water is an essential resource in human life, and the quality of water directly affects people's lives and health. Water hardness is an important indicator of water quality. The level of water hardness not only has a great impact on human health, but also has a great impact on life and industrial water. Testing water hardness can help us understand the water hardness situation, so as to take corresponding measures to ensure the quality of water and the use of effect.
MN's new AQUADUR TH 400 semi-quantitative water hardness test strips are designed with a single colour block for easier and more intuitive readings compared to multi-colour blocks. With the simple dip/read principle and a clear colour change from green to red, you get reliable results in seconds!
