Product Details

Instructions for using the ammonia nitrogen test kit

Specification Introduction:

Specification: 0.01-1mg/l

Testing frequency: 25 times/box

Shelf life: 1 year

Storage conditions: Room temperature, cool and dry place

Operating instructions:

Take a clean colorimetric tube and add the water sample to the 15mL mark of the tube. Add a packet of ammonia nitrogen reagent I and mix well to dissolve. Cover the tube and shake well to dissolve. After 2 minutes, add a packet of ammonia nitrogen reagent II and mix well to dissolve. After 15 minutes, open the lid and place the colorimetric tube in the blank of the colorimetric card to visually compare with the standard color scale from top to bottom. The same color scale as the solution in the tube is the content of ammonia nitrogen in water (mg/L)

Note: The test temperature is 10-30 ℃

Common interference:

1. The pH value should be controlled between 5-8.

2. Ammonium chloride is quantitatively measured under these conditions

3. Cations: calcium ions, magnesium ions, etc. Potassium sodium tartrate can be added for masking.

4. The color carried by the liquid itself can also cause interference. Activated carbon can be used for decolorization.

matters needing attention:

1This product is non-toxic, but please keep it out of reach of children.

2Accidentally touching the skin, rinse off with water.

The product is salicylic acid method
