Whether you’re evaluating a prospective client’s existing concrete for estimating purposes or you’re in the process of neutralizing a surface in preparation for resurfacing, Extech’s pH tester ExStik pH100 (aka the ExStik) is a fabulous tool for identifying problem areas. The “ExStik” can be calibrated to 4, 7 or and 10, and within ten minutes can store up to 15 separate pH readings. Take about 10 minutes to collect all as much data as you can, and then chart pH levels across your entire work area, and record them for future reference. With automatic temperature compensation and a waterproof housing that allows it to float in water, the accuracy of the “ExStik” provides an excellent safeguard against potential problems that could arise with your projects.
