CheckerŪ represents the latest generation of lightweight, pocket-sized pH testers to be specially designed and developed by Hanna Instruments. At the cost of a few rolls of pH litmus paper, you can now have the industry's most advanced electronic pH tester. CheckerŪ will supply you with fast and accurate readings on a large Liquid Crystal Display. Simply immerse the probe into your sample and read the pH value. Unlike other pH testers, the CheckerŪ electrode can be changed. Range 0.00 to 14.00 pH.
