Technical Features
- Suitable for many measuring tasks where ozone measurements for control purposes were too expensive to date, e.g. for leakage tests in industry, for protection of health and safety standards at work, for mobile air quality measurements etc.
- Each ozone sensor is supplied with a manufacturer’s test certificate.
- As a result of the high long-term stability, only small maintenance costs.
