Imported from GermanyMN 90420 pH Test Strip, belonging to MN's PEHANON series acid and alkali test strips. The indicator band and the color mark of the German MN ph test paper are printed on the same paper strip, which has the advantage of not spending time looking for another color mark to compare, and the color mark and the indicator band are also affected by the color of the liquid, so it is especially suitable for measuring the pH value of colored solutions or suspensions, with 200 strips per box and a size of 11x100mm.
The measurement range of MN 90420 ph test strip is 8.0~9.7pH, and the grid is 8.0-8.2-8.4-8.6-8.8-9.1-9.4-9.7pH.
