NPK & pH Combined Test Kit Hi3896 (25 Samples)Hanna Instruments
NPK & pH Combined Test Kit Hi3896 by Hanna is used not only to measure the soil's pH but also its nitrogen, phosphorus and potassium levels.
It is highly easy to use: once the soil sample is diluted in water, the chemical reagents included in the kit are to be added so that they can act on it. The colour of the resulting solution has to be compared with the reference chart included. pH is measured according to 6 different colours, from pH 4 to pH 9.
The professional kit HI 3896 comes with an extraction solution that makes it easier for suspended soils to fall so that measurements can be immediately carried out.
25 measurements can be done.
