Notes:
The test result can be converted into the following unit(s): FTU (same as FAU)
FAU stands for Formazin Attenuation Units, different from the NTU (nephelometric) method.
The measurement should be conducted immediately after sampling.
Air bubbles will influence the measurement result.
Tinted water samples influence the result. In this case do not use distilled water (step 1) but
rather filtered sample water for the ZERO adjustment.
