Liquid level CO2 concentration detector

The accuracy of the CO2 concentration control of the CO2 incubator is a key factor in cell culture. Modern CO2 incubators use electronic components with sensors to control the CO2 concentration. Although the accuracy is high, there are also complete failures and sensors that detect zero drift Phenomenon, so you need to use another simple and reliable method or instrument to detect, just like people often use simple but reliable mercury thermometers to detect and correct complex and accurate electronic thermometers. The CO2 incubator has detection holes, indicating that it needs to be tested by another instrument. Almost all modern CO2 incubators work after a period of time, the sensor zero drift may occur, therefore, its "product instruction manual" will require regular calibration of the zero, otherwise the displayed value may seriously deviate from the actual value. It takes several hours to correct the zero position each time, which affects the cell growth. Therefore, frequent CO2 concentration testing is the best way to ensure the normal use of CO2 incubators.
