Micro LPC 101 HP Gas Particle Counter

Question
In MLPC-101 HP specification the maximum particle sizing threshold is 5 micron. What is the reference to use these sizes in compressed air or nitrogen gas?

Answer

All MLPC-101 gas particle counters are calibrated with CDA (clean dry air) at pressures of 100 psi.

The non-gas MLPC-101 unit is calibrated with normal room air and ambient pressure (14.7 psi).
