The latest HI98103 Checker and HI98100 Checker Plus are the next generation of the original Hanna Checker pH tester. The Checker is by far one of the most popular pH meters in the world with over 1 million meters used since its introduction in 1991. From students to researchers, the Checker has been helping people with their pH measurements as a meter that is simple to use and operate.
These Checker pH testers have been designed with many advanced features while maintaining the look and feel of the original Checker. The HI98100 Checker Plus and HI98103 Checker now offer automatic calibration to one or two points, automatic buffer recognition, calibrated buffer tags, stability indicator, low battery indicator, and selectable automatic shut off. Both the Checker and Checker Plus maintain the iconic pentagon design with a probe measuring 103 mm in length that is tapered to an 8 mm diameter, making it ideal for measurements in test tubes and vials.
The supplied HI1271 pH electrode is 103 mm long and tapers to an 8 mm diameter at the sensing end to easily fit into test tubes, vials, and other containers with a small opening.
These meters are calibrated automatically to one or two points. The calibration buffers are automatically recognized and after calibration the buffer values used are shown on the display as a tag.
These Checkers have a long battery life of approximately 1000 hours. When the battery power is running low a battery indicator is displayed.
The Checker and Checker Plus are full-featured pH testers at an affordable price.
An hourglass indicator is displayed on the LCD until a stable reading is obtained. Once a reading stabilizes, the indicator disappears and a reading can be recorded.
The HI98100 and HI98103 are supplied complete with meter, probe, calibration solutions, and cleaning solutions packaged in a durable plastic carrying case.
The HI98100 Checker Plus features ±0.2 pH accuracy with 0.01 resolution while the HI98103 features 0.1 resolution.
Enhanced LCD that displays reading, stability indicator, low battery indicator, and calibration tags.
These meters can be set to automatically turn off after 8 minutes or 60 minutes to conserve battery life in the event that the meter is left on. The auto-off feature can also be disabled.
