Whether it is natural or technically produced near the ground, even at low concentrations, ozone in the ambient air has a high potential for damage. The observance of safe ozone limits is therefore not only required for the protection of health, but clearly regulated and prescribed by law in many countries. With the OZ-ONE Ozone Meter, you have the optimum test instrument for fast and precise control or long-term monitoring of ozone concentrations in the ambient air. The OZ-ONE is characterized by very low cross-sensitivity to other gases or VOCs and convinces by fast measurement results with high accuracy even at very low ozone concentrations.
