Item no. HI-98103
The HI98103 Checker 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 students to researchers, the Checker has been helping people with their pH measurement as a meter that is simple to use and operate.
Economical – The Checker is a full-featured pH tester at a price that anyone that needs to measure pH can afford.
Large LCD - Enhanced LCD that displays reading, stability indicator, low battery indicator and calibration tags.
Automatic Calibration - The Checker 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.
Long Battery Life - The Checker has an exceptional long battery life of approximately 1000 hours. When the battery power is running low a low battery indicator is displayed.
Replaceable pH Electrode - The HI1271 supplied gel filled pH electrode tapers to an 8 mm diameter at the sensing end. This narrow electrode easily fits into test tubes, vials, and other containers with a small opening.
