Have your pH readings displayed through a large LCD window down to a resolution of 0.01 pH.
Monitor your aquariums temperature and pH all with a single pen-style tester. Hanna's HI98108 Waterproof pHep+ Tester can give you pH readings from 0.00 all the way up to 14.0 pH making it perfect for saltwater or freshwater aquariums. The HI98108 can also monitor temperature, and the exposed temperature sensors allow for rapid automatic temperature compensated pH measurements.
Hanna has a unique reference cell design that utilizes an extractable cloth junction for the pH electrode. Cloth junctions are well known for creating clogs that can cause erratic and incorrect readings. By tearing a small portion of the cloth away from the meter, you will expose a fresh surface helping extend the life of the pH electrode. Calibration is even easier by pressing the dedicated calibration button. Once in calibration mode, you can select one or two points of reference using the preprogrammed buffer settings (4.01, 7.01, 10.01).
