The nickel has been recognized that is the latent irritant metal, it may cause the dermatitis of the human who is the allergy.If the nickel contacts the skin, it can stimulate the body immune response and cause rash, sometimes possibly causes the more serious immune response. The conventional test method is to deliver the sample to the laboratory for test, the time is long, the expense is high, the process is complex, has the destruction to the sample, the quantity is small, it can only test the samples, according to the above situations,we empoldered the nickel fast testing reagent cooperated  , it can carry on the fast screening test to the nickel ion.

Product characteristic:

1、Test the nickel on many kinds of material surfaces, for example: jewellery, watch,zipper, belt fastener and so on.

2、The test is rapid, the process is simple, the cost are inexpensive, the effect is obvious.

3、Use in the qualitative test of the material surface nickel content and should not be considered quantitative.

4、The harm of the measured material is small.
