Calibration

All microAeth instruments are flow calibrated at approximately standard atmospheric
pressure and room temperature to ensure accurate flow rates at the time of production.
Local operating conditions vary around the world. Temperature and pressure at the time of
calibration are recorded in the flow calibration table header. Before instrument deployment,
we suggest that the flow rates at the inlet of your microAeth instrument are checked.
In general, and especially for sampling at higher elevations, AethLabs suggests calibrating
the flow of your microAeth in the location at which you plan to use it. This will ensure that
the internal mass flowmeter is calibrated for the in situ atmospheric pressure.
If re-calibration is needed, it is possible to calibrate to within 1-2% on average using the
AethLabs MA Series Flow Calibration Kit. Only the external mass flowmeter provided in
the AethLabs MA Series Flow Calibration Kit is compatible with the MA200, MA300, and
MA350.
Cleaning & Maintenance
If the microAeth is exposed to any liquids or other damaging contaminants, immediately
turn off the instrument, disconnect all cables, and remove any foreign substances
in contact with the instrument. Do not use liquids or other cleaning products on the
instrument. Wait until the microAeth is completely dry before charging or turning on the
instrument. Only AethLabs authorized service personnel should clean the air passageways
and internal components of the microAeth.
AethLabs recommends sending your instrument for annual service, or more frequent
service depending on use and operating conditions. Cleaning intervals will vary based on
the sampling environment and concentrations.
In addition to any necessary repairs, AethLabs offers flow calibration service and standard
maintenance service (including full diagnostics, cleaning, flow calibration, and instrument
testing) at the AethLabs San Francisco office. AethLabs also has authorized repair
locations in Europe and South America.
