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 students to researchers, the Checker has been helping people with their pH measurement as a meter that is simple to use and operate.

Features at-a-glance:

Economical – The Checker Plus 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.

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.

Long Battery Life - The Checker Plus 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 HI98100 Checker Plus is supplied complete with meter, probe, calibration solutions and cleaning solutions packaged in a durable plastic carrying case.

Quick reading, price is fair

Initial calibration was a little confusing but still took less than 10 min
REVIEW
I have been using this for about a month. It is a great product seems to be very accurate and of course better than deciphering a titration style test kit
