*2
*1: Iron oxide has several isomers, as can be noted from the table above
there are substance that can be measured with the Grease Steel Dust
Meter and substance that can not be measured. Specially in case the
environment allows the oxidation of iron particles easily and where the
collected sample contains red rust the measurement conduct may
indicate a reading lower than the actual concentration.
*2: When the grease contains a filler agent, the Grease Steel Dust Meter
does not have any sensitivity against such substance, and does not
affect the measured reading.
