HANNA Checker and Checker Plus pH Testers

The HANNA Checker® and Checker Plus pH Testers are designed for direct measurement, bringing simplicity to pH testing during any process. A replaceable electrode extends the life of the tester. An onscreen stability indicator ensures the highest level of confidence in results. The selectable auto-off feature prolongs battery life for peace-of-mind and energy savings if the meter is accidentally left on. The compact size makes the Checker pH tester ideal for on-the-go testing. A large LCD display provides at-a-glance readings from any angle and single button operation streamlines the testing process for any user.

Testers come with cleaning solution engineered to keep the electrode free from build-up, single-use pH 4 & 7 buffer sachets for a fresh buffer each time users calibrate, and storage solution for proper storage ensuring reliable measurements and a long electrode life.
