The HI-96739 meter measures the fluoride content in water, wastewater and seawater in the 0 to 20 mg/L (ppm) range.
This photometer uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell. It is designed to fit cuvettes with a larger neck making it easier to add both sample and reagents. The cuvettes are made from special optical glass to obtain best results.

PLEASE NOTE: | In some cases, samples may contain other parameters which may interfere with results | |
Negative Interference may be caused by: | Alkalinity (as CaCO3) above 5000 mg/L; Aluminium above 0.1 mg/L; Iron, ferric above 10 mg/L | |
Positive interferences may be caused by: | Chloride above 700 mg/L; Phosphate, ortho above 16 mg/L; Sodium hexametaphosphate above 1.0 mg/L; Sulphate above 200 mg/L; Highly coloured and turbid samples may require distillation; Highly alkaline samples can be neutralised with nitric acid |
