How Often to Change the Water in the Polarcept Filter
How many measurements can we conduct in monitor mode before you would recommend changing the water in Chamber In?
This is with the consideration that we are running monitor mode with the following Polarcept settings: measure for 6 minutes and cleaning for 12 minutes.
The frequency that a user should change their Polarcept filter water is completely dependent upon the environment in which they are performing measurements. Environments with high VOC concentrations (from engine fumes, solvents/cleaning agents, etc.) will saturate the water in the Polarcept much more rapidly than environments with low VOC concentrations. As a best practice, users should change their polarcept filter water at least once every day prior to use. If the user notices an upward drift in their readings over time, that is also a good indicator that the polarcept water needs to be changed.
