Features at-a-glance
-
Economical - The PH128 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 PH128 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 PH128 has an exceptional long battery life of approximately 1000 hours. When the battery power is running low a low battery indicator is displayed.
-
Plastic Carrying Case – The PH128 is supplied complete with meter, probe, calibration solutions and cleaning solutions packaged in a durable plastic carrying case.
