Description
The Ohaus Starter ST2200 is a benchtop pH meter built for routine pH, ORP, and temperature measurement in laboratory, educational, food processing, and water treatment settings. It pairs a straightforward keypad interface with automated calibration features, making it a practical choice for labs that need dependable, no-frills pH readings without a steep learning curve. The meter stores up to 99 measurement sets in internal memory and ships with a built-in electrode holder for streamlined bench setup.
Features:
- Auto Buffer Recognition: automatically identifies the calibration buffer in use, removing a manual setup step and reducing calibration errors.
- Auto-Endpoint Detection: signals when a stable reading has been reached during calibration or measurement, speeding up throughput for routine testing.
- Multi-Point Calibration: supports up to 3-point calibration for improved accuracy across the full pH range.
- Backlit LCD Display: a 3.5-inch segment display with backlighting keeps readings legible under variable lab lighting conditions.
- Built-In Electrode Holder: integrated arm mount keeps the electrode positioned and stable during use, reducing bench clutter.
- Internal Memory: stores up to 99 measurement sets, useful for logging routine QC checks without an external data logger.
- Two Variant Options: the ST2200-F ships complete with an ST320 pH electrode and buffer mini-kits, while the ST2200-B is sold without an electrode for labs standardizing on their own probes.
