Hanna Instruments Checker Plus pH Tester
HI98100 Checker® Plus pH Tester
The HI98100 Checker Plus is the next generation of the original Hanna Checker pH tester. The Checker is the most popular pH meter in the world with over 1 million meters used since its introduction in 1991. From entry-level growers to professional horticulturalists, the Checker has been helping people with their pH measurement as a meter that is simple to use and operate.
The HI98100 Checker Plus pH tester has been designed with many advanced features while maintaining the look and feel of the original Checker. The Checker Plus now offers automatic calibration to one or two points, automatic buffer recognition, calibrated buffer tags, stability indicator, low battery indicator, and selectable automatic shut off.

Economical - The Checker Plus is a full-featured pH tester at a price that anyone that needs to measure pH can afford.

Replaceable pH Electrode - The HI1271 supplied gel filled pH electrode is 103 mm long and tapers to an 8 mm diameter at the sensing end. This narrow electrode easily fits into test tubes, vials, and other containers with small opening.
Automatic Calibration - The Checker Plus is 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.
Stability Indicator - An hourglass indicator is displayed on the LCD until a stable reading is obtained. Once a reading stabilized the indicator disappears and a reading can be recorded.
Automatic Shut-Off - The meter 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 be disabled.
