NO Sensor

Nitric oxide is a colorless and odorless toxic gas at room temperature.Because nitric oxide contains free radicals that make it very reactive, it is easily oxidized in air to form the corrosive gas nitrogen dioxide.As a toxic gas, nitric oxide will not only damage human respiratory tract, but also do great harm to the environment, which is one of the main components of air pollution.With the increasing importance of environmental protection in China, nitric oxide sensors will play an important role in emission detection and air quality monitoring.

The no sensor USES an electrochemical method of detection. Unlike traditional electrochemical detection, the product increases the number of internal electrodes of the sensor to 3-4.In order to ensure the performance of the measurement, the electrode material of the sensor is selected carefully to play the role of catalytic reaction.Three electrodes are designed to stabilize the working voltage of the induction electrode.Selective use of filters to separate gases that may interfere with measurements;In addition, to further eliminate cross-interference and temperature-induced baseline drift, a fourth electrode was added to some nitric oxide sensors.The measurement performance of no sensor is guaranteed by the above technologies.
