Nitrite Test Kit

1. Specification
Name: Nitrite Test Kit
Model: LH-P*1
Type: semi-quantitative
Color reaction: none- purple
Gradation: 0.***0.***0.***0.**0.**0.**0.**0.5mg/L (NO*-)
Packaging detail: *0units/box
Shelf life: at least 1 year
Applications: Nitrite test kits are ideal to use for water control due to the quick and easy procedure, also important in quality controls of food, e.g. meats and spinach. Excessive amounts of nitrite can potentially be harmful to consumers, especially to infants.
2. Features of product
Easy to Operate: Users do not require special training, and can refer to the use instruction on the colorimetric card, and independently finish water testing in *5 minutes per water sample.
Accurate Measuring: Testing methods are under international standards.
Convenient Packs: small size, lightweight and convenience for carrying.
3. Operation
1. Fill the tube with *5mL testing liquid, add one pack of the reagent I, wait for 5 minutes, add one pack of reagent II, wait for *0 minutes,
2. Put the tube on the colorimetric chart, and look from up to bottom, compare the color of the liquid and colors on the chart, then come out a result (mg/L).
Note:
1) Oxidant and reductant will affect the result.
2) Cu2+, Fe2+ and nitrate will lower the result.
3) Lead, Mercury and Silver ion will create sediment with reagent, eliminate the interference before testing.
4. Background of development
Nitrite is a contamination indicator and therefore an important parameter that is tested regularly in a wide variety of settings. To determine the nitrite concentration, very often nitrite test kits are used. 
Nitrite is an undesired byproduct in cooling lubricants. It allows the formation of carcinogenic compounds. Cooling lubricants are therefore regularly tested with nitrite test kits.
Additionally, nitrite is an important parameter for aquacultures and fish farming. Nitrite is formed in the decomposition of organic material. High levels can lead to the disruption of filtration units. Moreover, long-term exposure can be harmful to fish. In natural and drinking water Nitrite can lead to infant mortality and dead aquatic life. The EPA primary drinking water standard is 1 mg/L. Nitrite test kits are ideal to use for water control due to the quick and easy procedure.
Nitrite test kits are also important in quality controls of food, e.g. meats and spinach. Excessive amounts of nitrite can potentially be harmful to consumers, especially to infants.
