| abstract | PROBLEM TO BE SOLVED: To provide a NOx concentration measurement technique capable of continuously and accurately measuring a predetermined NOx concentration in a gas to be measured without being affected by an oxygen concentration or a change thereof. SOLUTION: In order to know a predetermined NOx concentration in a gas to be measured, a first internal space 6 into which a gas to be measured is guided through a first diffusion-controlling passage 12, and an atmosphere thereof is a second diffusion-controlling passage. 14, a first oxygen pump means for controlling the partial pressure of oxygen in the first internal space 6, and a second oxygen pump for pumping oxygen in the second internal space 8. Two oxygen pump means and current detecting means 32 for detecting a pump current flowing by the operation of the second oxygen pump means are provided. Then, the NOx concentration in the gas to be measured is obtained from the value of the pump current Ip detected by the current detecting means 32. [Selection] Figure 2 |
