Hanna - pH Tester HI98103 Checker

The Hanna pH Tester HI98103 Checker supplies users with fast and accurate readings from 0 to 14 pH with a resolution of 0.1 pH. This compact tester features an easy to read LCD and simple to perform two-point calibration.

The ph electrode of the checker can be easily replaced. You only need to unscrew the electrode from the meter body and screw on a new one. The Checker is fast, accurate, lightweight and with 3000 hours of battery life, you don't have to worry about frequent battery replacement.


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.
