PRODUCT INFORMATION PRODUCT INFORMA TGS 4161 - for the detection of Carbon Dioxide Features: Applications: * High selectivity to CO2 * Indoor air quality control * Compact size * CO2 monitors * Low dependency on humidity * Long life and low cost * Low power consumption TGS4161
is a new solid electrolyte CO2 sensor which offers miniaturization and low power consumption. A range of 350~10,000ppm of carbon dioxide can be detected by TGS4161, making it ideal for indoor air control applications. The CO2 sensitive element consists of a solid electrolyte formed between two electrodes, together with a printed heater (RuO2) substrate. By monitoring the change in electromotive force (EMF) generated between the two electrodes, it is possible to measure CO2 gas concentration. The top of the sensor cap contains adsorbent (zeolite) for the purpose of reducing the influence of interference gases.
TGS4161
exhibits a linear relationship between ∆EMF and CO2 gas concentration on a logarithmic scale. The sensor displays good long term stability and shows excellent durability against the effects of high humidity. The figure below represents typical sensitivity characteristics The figure below shows typical humidity dependency of of TGS4161. The Y-axis is indicated as ∆EMF which is defined TGS4161. Again, the Y-axis is indicated as ∆EMF which is as follows: defined as follows: ∆EMF=EMF1 - EMF2 ∆EMF=EMF1 - EMF2 where where EMF1=EMF in 350 ppm CO2 EMF1=EMF in 350 ppm CO2 EMF2=EMF in listed gas concentration EMF2=EMF in 1000ppm CO2
Sensitivity Characteristics: Humidity Dependency:

IMPORTANT NOTE:
OPERATING CONDITIONS IN WHICH FIGARO SENSORS ARE USED WILL VARY WITH EACH CUSTOMER’S SPECIFIC APPLICATIONS. FIGARO STRONGLY RECOMMENDS CONSULTING OUR TECHNICAL STAFF BEFORE DEPLOYING FIGARO SENSORS IN YOUR APPLICATION AND, IN PARTICULAR, WHEN CUSTOMER’S TARGET GASES ARE NOT LISTED HEREIN. FIGARO CANNOT ASSUME ANY RESPONSIBILITY FOR ANY USE OF ITS SENSORS IN A PRODUCT OR APPLICATION FOR WHICH SENSOR HAS NOT BEEN SPECIFICALLY TESTED BY FIGARO.
