- instructions

OBSERVATIONS:
In the water treatment market often speaks of "nitric azote" (which corresponds to nitrates), of "nitrous azote" (which corresponds to nitrites), and "ammonia azote" (which corresponds to ammonia), however the concentrations are expressed as NO3 for nitrates, as NO2 for nitrites and as NH3 for ammonia.
The IPT kits are ideal in cases where you need to make little analysis, with reasonable accuracy. For many analysis and great accuracy the HYDROCHECK, which also offer a lower cost for analysis.

INSTRUCTIONS FOR USE
1. Rinse the test tubes well whit the water to be analysed.
2. Put the color scale on a plain surface whit good illumination (not direct sunshine).
3. Put 5 ml. of the water to be analysed into both the test tubes. Insert one test tube (blank) into one hole of the comparator and put it on the color scale whit the blank on the color fields.
4. Measure 5ml. of the water to be analysed with the second (empty) test tube.
5. Add on level spoon of Nitrate reagent to the test tube, replace top and shake well for one minute.
6. Swirl well and put the test tube into the empty hole of the comparator.
7. After 5 minutes compare the color whit the chromatic scale, moving the comparator backwards and forwards. Find the best meeting color and read the Nitrate value directly on the scale.
