Potassium Ion Test Kit (Test Strip Method)

The OFITE Potassium (K⁺) test is suitable as a rapid guiding test for potassium in water, drilling fluids, and extracts from soil samples. A particular advantage of the test is that potassium can be semi-quantitatively determined in the presence of 10 times its amount of sodium. The test strips have a color scale graduated as follows: Range: 0 - 300 - 700 -1,000 - 2,000 mg/L (ppm) K⁺. The test is a very simple procedure. Immerse the strip briefly in the sample solution, shake off excess moisture, immerse for 1 minute in 0.7% nitric acid, and compare the color with the color scale. The plastic box contains 100 test strips.
