Bubbles in the Sample
If bubbles are present in the sample water the readings may appear higher than expected. These
reading may also not be stable.
Remove cuvette if air can be seen coming into the flow-through unit from the inlet tube, this is air
introduced, probably from a small water or air leak. This will need to be resolved in the plumbing.
If air cannot be seen entering the intake tube but appears on the inside of the glass cuvette, it is
coming out of solution. This can usually be cured by applying pressure to the rotary backpressure
