Description
The Ohaus Starter 2100 is a user-friendly benchtop pH meter designed for accurate, reliable pH and ORP measurements in basic laboratory, educational, and industrial settings. Built with simplicity in mind, it allows even novice users to operate the instrument confidently with minimal training, thanks to its clearly labeled controls and an attached quick-reference guide built into the housing. The meter comes equipped with a built-in electrode holder, enabling a clean, all-in-one setup that keeps the workspace organized and reduces the risk of electrode damage between uses. A large, easy-to-read LCD display presents pH, mV, or temperature readings clearly, while features like auto buffer recognition and automatic temperature compensation help ensure consistent, accurate results without requiring manual calculations. Whether used for routine quality control, teaching lab exercises, or general sample testing, the Starter 2100 offers dependable performance at a cost-effective price point, making it a practical choice for labs that need straightforward, no-frills pH measurement capability.
Features:
- Auto Buffer Recognition — Automatically identifies standard calibration buffers, simplifying the calibration process and reducing user error.
- 1- or 2-Point Calibration — Supports flexible calibration routines, with 2-point calibration recommended for improved measurement accuracy across a wider pH range.
- Automatic Temperature Compensation (ATC) — Adjusts pH readings based on sample temperature (when used with a compatible temperature probe) to ensure accurate results regardless of fluctuations.
- Electrode Condition Icon — Displays real-time electrode health based on slope and offset values, helping users know when maintenance or replacement is needed.
- Built-In Electrode Holder — Keeps the electrode securely positioned and protected during use and storage, supporting a clean, all-in-one benchtop setup.
- Large LCD Display — Clearly presents pH, mV, and temperature readings for quick, easy interpretation.
- Attached Quick Guide — A built-in reference guide stored in the housing allows users to access setup and operating instructions without hunting for a separate manual.
