Ammonia Nitrogen Rapid Test Kit, 0-20mg/L

Estimated delivery : 30 Days; MOQ : 1 Box (1 Box = 100 Times)
The rapid test series is a semi-quantitative test product. The test results are interval values, so there is no concept of precision or accuracy. The sensitivity is the minimum detection limit.
Widely used in rapid on-site detection of water quality in urban water supply, food and beverage, environment, medical, chemical, pharmaceutical, thermal power, papermaking, breeding, bioengineering, fermentation technology, textile printing and dyeing, petrochemical, water treatment and other fields

Basic features :

1. Ability to detect indicators and read data in a relatively short time
2. Simple operation, no other accessories required
3. Easy to carry, suitable for on-site testing
4. Cheap

I. Ammonia nitrogen test paper 0-20 operation:
a. Take 1 ml of water sample and add it to the matching small test tube
b. Add 1 drop of matching activator to the test tube and shake well.
c. Take out the test paper and quickly cover it
d. Immerse the test paper reaction area in the water sample for 5 seconds, take it out and shake off the excess water sample.
e. After leaving it for 2 minutes, compare it with the colorimetric card. The color block with similar color is the concentration value of the sample being tested.

II. Ammonia nitrogen test paper 0-100 (code 01.01.0007) operation:
a. Take out the test paper and quickly cover it
b. Immerse the test paper reaction area in the water sample for 2 seconds, take it out and shake off the excess water sample.
c. Add 1 drop of activator to the reaction end and shake off the excess water droplets after 15 seconds.
d. After 60 seconds, compare it with the color card. The color block with similar color is the concentration value of the sample being tested.

III. Ammonia nitrogen test paper 0-100 (code 02.01.2001) operation:
a. Take 1 ml of water sample and add it to the matching small test tube
b. Add 4 drops of matching activator to the test tube and shake well.
c. Take out the test paper and quickly cover it
d. Immerse the reaction area of ​​the test paper in the water sample to be tested for 10 seconds, take out the excess water sample and immediately compare it with the colorimetric card. The color block with a similar color is the concentration value of the sample to be tested.

IV. Ammonia nitrogen test paper 0-400 operation:
a. Take 1 ml of water sample and add it to the matching small test tube
b. Add 4 drops of matching activator to the test tube and shake well.
c. Take out the test paper and quickly cover it
d. Immerse the test paper reaction area in the water sample for 10 seconds, take it out and shake off the excess water sample.
e. Compare with the color card, the color block with similar color is the concentration value of the sample being tested.

V. Ammonia nitrogen test paper 50-500 operation:
a. Take 1 ml of water sample and add it to the matching small test tube
b. Add 1 drop of matching activator to the test tube and shake well.
c. Take out the test paper and quickly cover it
d. Immerse the reaction area of ​​the test paper in the water sample to be tested for 2 seconds, take it out and shake off the excess water sample.
e. After leaving it for 10 seconds, compare it with the colorimetric card. The color block with similar color is the concentration value of the sample being tested.

VI. Ammonia nitrogen test paper 0-1000 operation:
a. Take out the test paper and quickly cover it
b. Immerse the test paper reaction area in the water sample for 2 seconds, take it out and shake off the excess water sample.
c. Add 1 drop of activator to the reaction end and shake off the excess water droplets after 15 seconds.
d. After 60 seconds, compare it with the color card. The color block with similar color is the concentration value of the sample being tested.

Note:
a. When taking out the test paper, do not touch the front reaction area of ​​the test paper with your fingers to avoid contaminating the test paper and affecting the detection.
b. Store in a cool and dry place. After taking out the required test paper, the bottle cap should be tightly closed in time to prevent the test paper from being exposed to moisture or oxidation in the air for a long time.
c. The liquid to be tested must be colorless or light-colored. Colored liquids must be decolorized before testing (solution decolorization: activated carbon adsorption method or dilution method)
d. If the liquid to be tested is turbid, let it stand for a while and then take the clear part for testing.
e. The pH of the liquid to be tested should be within the specified value. If it exceeds the range, it should be adjusted in advance.
f. The color comparison must be completed within the specified time. If the test result exceeds the specified time, it will be invalid.
g. If the concentration of the liquid to be tested exceeds the detection range, dilute it with distilled water before testing.
