RAINBOW / Water quality testing


In many developing countries, the government does not build good infrastructure to provide
clean drinking waterfor the people. Around the world, more than 6,000 people die every day
because of dirty drinking water.The hope is to provide these people with a cheap, simple,
repeatable product for identifying water quality.
Our products use TDS technology to simplify complex operations, and use different colors to guide
users to operate, eliminating the barriers between different languages and cultures, so that the
products can be accepted by users without good education.
