Semi-quantitative analysis is performed by utilizing a specific reaction between test paper containing a color reagent and ions in the sample solution.
To measure, simply dip the test strip into the test liquid and compare the degree of color change with the color scale on the outer box.
Only a small amount of sample is required, and the ion selectivity is excellent.
The test paper attached to the end of the plastic stick (0.2 mm thick) is the same size as the color scale, making color comparison very clear. Measurement items: NO2^-
Product name: Nitrous acid
Measurement range: 0-1-5-10-20-40-80mg/L
Discoloration: White to reddish purple
Quantity: 1 box (100 sheets)
QUANTOFIX
*Dilution is required when the concentration exceeds the scale, and removal treatment is required if there is a possibility of interfering ions.
