Abstract

A CO₂ sensor was set up by using Na₃Zr₂Si₂PO₁₂ (NASICON) as a solid electrolyte, Li₂CO₃ as a carbonate phase. The EMF (Electromotive force) was linear to the logarithm of CO₂ concentration and hardly depended on interfering gases by using a zeolite filter. The Δ EMF (EMF_Air-EMF_Gas) was stable even after the test of unpowered exposure to a high humidity atmosphere. The CO₂ monitor in which the CO₂ concentration is calculated by the Δ EMF using a new renovating system of the standard EMF was developed as a monitor for air quality control. The output of the monitor indicated a good agreement with that of the usual NDIR analyzer at the field-test in the office.
