Oxygen Sensor | Apogee Instruments

Voltage output is linearly proportional to absolute amount of oxygen. Calibration is accomplished by measuring the voltage under ambient conditions (atmosphere is % O 2 and deriving a linear calibration factor (slope). A zero offset can be measured with N 2 gas (recommended for measurements below 10 % O 2).

CO2 Sensors for Life Science Incubators |

Carbon Dioxide (CO2) absorbs the wavelength within the infrared portion of the electromagnetic spectrum. An IR emitter then directs the infrared light through a sample of the growth chamber's atmosphere, then through an interferometer filter that isolates the proper wavelength and finally allows the sensor to process the data.
