•

Press the 

Zero 

key. The display will show “

-0.0-

” when the meter is zeroed and ready for

measurement.

•

Remove the vial.

•

Remove the cap and add the content of one packet of HI 93766-0 Nitrate
Reagent.

•

Replace the cap tightly and invert the vial 10 times. This is the reacted
sample.

Note

: The method is technique sensitive: to obtain most reproducible results

it is strongly recommended to follow carefully the “invert” procedure
described on page 10.

•

Place the vial into the holder and push it completely down.

• Press 

Timer 

and the display will show the countdown prior to the measurement and the ”

Reaction

Time

”

 

message. Alternatively, wait for 5 minutes and press 

Read

. The instrument will perform the

reading.

• The instrument displays concentration in 

mg/L of nitrate-nitrogen (NO

3

--N)

. Press 

s

 or 

t

 to

convert the result in mg/L of nitrate (NO

3

-).

INTERFERENCES

Interference may be caused by:
Barium (Ba

2+

) above 1 mg/L

Chloride (Cl-) above 1000 mg/L
Nitrite (NO

2

-) above 50 mg/L

Samples containing up to 100 mg/L nitrite may be measured after the following treatment: add 400 mg
of urea to 10 mL of sample, mix until completely dissolved, then proceed with the usual measurement
procedure.
