Checker pH Testers

Click to enlarge

At the cost of a few rolls of pH litmus paper, you can now have the industry's most advanced electronic pH tester. Unlike other pH testers, the checker electrode can be changed and virtually any screw-type pH electrode can be used. Checker 1 is supplied with a rugged epoxy pH electrode. It offers a wide range of 0-14 pH with 0.01 resolution, and accuracy better than 0.2pH. Runs on two 1.4 volt batteries. Dimensions: 66 x 50 x 25mm.
