Basically fertilizer measurement/ test method is kolorimetri, based on
to the handbook of indonesia national standard, that include fertilizer
type such as: NPK, KCL, Urea, Amonium Phospat, etc. Macro elements that
can be tested by this measurement test with NPK Digital Tester, is:
1. Nitrogen ( n) With fertilizer sample destruction using strong acid will produce ammonium salt compound, and then color development proceed with nesslerisasi direct in alkali atmosphere and it will gain complex yellow colored with the color sharpness the same as nitrogen as in example.
2. Phospor Posphates content in exhibit determine based on its reaction
with ammonium molbovanadat forming complex yellow colored, with the
color enhancement equal to its phospat content.
3. Kalium ( k) content Kalium content in fertilizer reacted with stable cobalnitrit compound with color enhancement equal to kalium within exhibit.
Tools characteristics:
1. ON/ OFF switch ( type of test method)
2. Zero adjust lever
3. Exhibit tray
4. Switch
5. Digitally test result display Fertilizer measurement tools specifications:
