These are easy to use, pH buffers for calibration of your Extech pH meter. These buffer solutions are available in either kit form or in one pint bottles (2 bottles per order).

The pH buffer kits includes 6 pouches of each buffer (pH 4.00, 7.00, and 10.00) plus 2 rinsing solutions. The rinsing solution should be used to clean off the pH electrode before taking the next measurement from a different solution to prevent contamination. A helpful table is included which shows what the pH value should be vs. the temperature of the buffer solution measured. A convenient pouch is also included to eliminate the need for a cup to store buffer or rinsing solution.
