pH Test strips, 4 - 9 pH units

Товар #: 2745650

Most natural waters range from pH 4 to pH 9, but commonly are above pH 7 because of carbonates and bicarbonates (alkalinity). The pH of water used in industry, boiler feed water, and swimming pools usually is kept within a narrow range. Contains 50 tests.

  • Easy to use, disposable, and inexpensive
  • Great for quick evaluations of pH levels in the lab or in the field
