AMMONIA LOW RANGE

SPECIFICATIONS

Range

0.00 to 3.00 mg/L (as NH

3

-N)

Resolution

0.01 mg/L

Precision

±0.03 @ 1.50 mg/L

Typical EMC

±0.01 mg/L

Deviation
Light Source

Tungsten lamp with narrow band interference filter
@ 420 nm

Method

Adaptation of the 

ASTM Manual of Water and

Environmental Technology, D1426-92, Nessler
method. The reaction between ammonia and
reagents causes a yellow tint in the sample.

MEASUREMENT PROCEDURE

• Select the program number corresponding to Ammonia LR on the

secondary LCD by pressing PROGRAM t and s.

• Remove the cap from a Reagent Vial.

• Add exactly 5.0 mL of sample to the

vial, while keeping the vial at a 45-
degree angle.

• Replace the cap and mix by inverting

the vial a couples of times. This is
the blank.

Method

Adaptation of the EPA method 365.2 and 

Standard

Methods for the Examination of Water and
Wastewater, 20

th

 edition, 4500-P E, ascorbic acid

method. A mild acid digestion converts condensed
inorganic forms of  phosphates to orthophosphate.
Then the reaction between orthophosphate and
the reagents causes a blue tint in the sample.
