4.2 Choosing a Location
To ensure that your AquaLab operates correctly and consistently,
place it on a level surface. This reduces the chance that sample ma-
terial will spill and contaminate the sample chamber. Also select a
location where the temperature remains fairly stable to avoid tem-
perature changes that can affect accuracy. This location should be
well away from air conditioner and heater vents, open windows, etc.
Place the AquaLab in a location where cleanliness can be maintained
to prevent contamination of the sample chamber.
