1、 Introduction to Ozone/Nitrogen Dioxide Sensor OX-A431
The OX-A431 sensor is a new replacement product based on the original O3-A421 sensor, with a larger range and the ability to detect O3 and NO2. If both gases are present in the environment, to accurately quantify O3, it is recommended to add NO2-A43F for correction and compensation; If there is only one of the two gases, the gas concentration can be directly quantified.

2、 Technical parameters of ozone/nitrogen dioxide sensor OX-A431 for detecting ozone
Response time:<45 seconds
Size: Φ 20.2 × 16.5
Ozone detection range: 20ppm
