Y-NH-4N Ammonia nitrogen tester
Product type:
Y-NH-4N
Product Instruction:
The instrument adopts
Nessler's colorimetry measurement of
ammonia nitrogen in water, and the
method has the advantages of simple
operation, high sensitivity. The
principle is that the free ammonia or
ammonium ions and other forms in the
presence of ammonia and sodium reagent
reacts to yellow brown complex, the
complex of the chroma and ammonia
content is directly proportional.
Equipment widely used in
surface water, industrial wastewater,
sewage and other water quality
measurement.
Technical parameters:
1. Measurement range:
0.02-10mg/L
2. The intrinsic error:
＼
3%
3. The minimum detection
limit: 0.01mg/L
4. Working temperature: 5
~ 40≧
5. Size: 282mm〜237mm〜102mm
6. Weight: 2.2kg
Main characteristics:
1. To be use of V/F
conversion, digital filtering
technology. It has the advantages of
strong anti-interference ability and
high stability.
2. Using the national
standard method (GB7479-87), directly
display ammonia nitrogen content.
3. Fast analysis speed
and high accuracy.
4. The parameters of
power can be saved automatically, can
not loss data.
