The GasLab® Pro 25% Oxygen Sampling Data Logger (CM-1000-00-00-52-00) is designed to measure oxygen levels over time in enclosed environments, used primarily in life sciences, incubation, scientific and medical applications. 

Utilizing a micropump, the device will draw samples into the sensing chamber allowing each sensor to take a fast and accurate measurement of the sample. This unit can also be programmed to measure at specific intervals, draw gas for a programmable period of time from the inlet port, expel it from the outlet port, and log the O2 values with a time stamp.

Users can view real-time data from the graph on the screen, as well as retrieve and analyze the data stored on the 16GB SD card. 

Please Note: **The SD Card Contains Important Calibration Information, Do NOT remove files from the SD Card until you have thoroughly read and saved the calibration information. If a calibration certificate is required it must be requested at the time of purchase. Thank you.**
