Re: Altitude correction for air samplers

Paul;

You indicate that you already perform a correction calculation for local
pressure and temperature changes. This answers your question. Your device
must not be self-correcting for pressure and temperature. Since these are
the only relevant parameters that may change with altitude, you will have
to make the same correction calculation.
