I suggest that you contact MET LABS in Union City California. Their "Dust Man" is really a good man and would probably offer you advice. I have forgotten his name but you can reach him through Troy Franklin 888-638-9345

We have a shelf system that is failing GR-63 hygro dust with excessive bit errors (unit did pass Gaseous contaminants no problem). Air is filtered. Anyone have experiences that they would like to share (non-proprietary of course) about how to trouble-shoot and solve this problem? This was the only GR-63 test to have a failure. Regards, John K.
