).
• Press s or t to return to the measurement screen.
INTERFERENCES
Interference may be caused by:
Iron above 50 mg/L
Silica above 50 mg/L
Silicate above 10 mg/L
Copper above 10 mg/L
Hydrogen sulfide, arsenate, turbid sample and highly buffered samples also interfere.
Phosphate LR
PHOSPHATE LOW RANGE
SPECIFICATIONS
Range 0.00 to 2.50 mg/L
Resolution 0.01 mg/L
Accuracy ±0.04 mg/L ±4% of reading at 25 °C
Typical EMC Dev. ±0.01 mg/L
Light Source Tungsten lamp with narrow band interference filter @ 610 nm
Method Adaptation of the Ascorbic Acid method. The reaction between phosphate and the
reagent causes a blue tint in the sample.

MEASUREMENT PROCEDURE
• Select the
Phosphate LR
method using the procedure
described in the
Method Selection
section (see page 12).
• Rinse, cap and shake the cuvette several times with
unreacted sample. Fill the cuvette with 10 mL of sample
up to the mark and replace the cap.
• Place the cuvette into the holder and close the lid.
• Press the Zero key. The display will show “-0.0-” when the meter is zeroed and ready for
measurement.
• Remove the cuvette and add the content of one packet of
