Using a pH meter is much more accurate than simple urine reagent strips. Fast, easy and highly accurate calibration: 0.2pH at 68°. High resolution: reads down to 0.01 pH units. Only a small sample required and will fit into a small container. Economical, lightweight design: 2 1/2 oz with 6" electrode. Battery operated with 3000 hour life. Kit includes pH meter, screw-on-electrode, buffer kit, and storage solution.

Note: All pH meters need to be calibrated, and should be stored in the 'electrode storage solution'.
