Checker / Product


The checker is a portable and durable device that allows the user to know the level of contamination in the air and in the water, helping him to make decisions that preserve his health.

Their use can improve the quality of life of millions of people living in heavily polluted cities, as well as the lives of people in unfamiliar environments.
