Ohaus ST2200-B Starter™ 2200 pH Bench Meter

The Ohaus ST2200-B is designed for routine pH testing in laboratories, schools, water treatment facilities, food processing, and industrial quality control applications. It is ideal for measuring pH, ORP (oxidation-reduction potential), and temperature in liquids and chemical solutions with dependable accuracy.

No. The ST2200-B version is supplied without a pH electrode, allowing users to choose the electrode that best matches their testing application. This flexibility is useful for laboratories that already own compatible probes or require specialized electrodes for certain sample types.

The Ohaus ST2200-B measures from 0.00 to 14.00 pH with a resolution of 0.01 pH and accuracy of ±0.01 pH. It also measures ORP from -1999 to 1999 mV and temperature from 0°C to 100°C, making it suitable for a wide range of routine laboratory applications.

The ST2200-B includes a large backlit LCD display, simple keypad controls, automatic buffer recognition, and auto-endpoint functionality to simplify calibration and measurement procedures. Its built-in electrode holder and guided operating interface help improve workflow efficiency for everyday laboratory use.

Yes. The Ohaus ST2200-B can store up to 99 measurement results along with calibration information for convenient recall and documentation. This built-in memory feature helps laboratories improve recordkeeping and maintain organized testing workflows.
