a. Oxygen range is relative to surface saturation.

 

b. +/- 0.2 mg/l or 2% of reading, whichever is greater.

 

c. Available measurement ranges:

• 0–30 μg Chl/l, 0–10 NTU

• 0–50 μg Chl/l, 0–25 NTU

• 0–50 μg Chl/l, 0–100 NTU

• 0–75 μg Chl/l, 0–200 NTU

• 0–125 μg Chl/l, 0–350 NTU

• 0–250 μg Chl/l, 0–1000 NTU

d. Chlorophyll fluorescence is created by living organisms and is subject to taxonomical and physiological changes. Field calibration is highly recommended. See user’s guide for standard protocols.

 

e. Depth rating is the lesser of 200 m or the pressure sensor rating.
