Experience exceptional precision and a high level of performance with the Orion™ Star A325 pH, Conductivity, and Temperature Portable Waterproof Multiparameter Meter. This versatile device is engineered for various applications, allowing you to measure pH, mV, ORP, conductivity, total dissolved solids (TDS), salinity, resistivity, and temperature effortlessly. The meter is built to withstand tough conditions, featuring IP67-rated waterproof housing, making it perfect for fieldwork in demanding environments. It allows simultaneous measurement of pH and conductivity, or you can view results separately, aiding in efficient data analysis. Store up to 5000 data points with comprehensive time/date stamps for convenient record-keeping and flexible data transfer options to printers or computers.
Key Features:
- Large, backlit graphic LCD display for easy reading, showing individual or all results simultaneously.
- Provides essential information including electrode status, time, date, sample ID, user ID, and calibration points.
- Advanced averaging and stability features ensure laboratory-level accuracy in the field.
- User-friendly interface with plain language screen prompts and soft keys for effortless selection.
- Multilanguage support in English, Spanish, French, Italian, German, and Chinese to cater to diverse user needs.
Benefits:
- Thermo Scientific™ AUTO-READ™ feature locks stable readings, ensuring accurate data capture.
- Up to five-point pH calibration with auto-recognition for USA/NIST™ and DIN buffers for unmatched flexibility.
- Quickly correct pH calibration errors without the hassle of complete recalibration.
- Selectable cell constant compatible with both 2-cell and 4-cell conductivity cells for tailored performance.
- Choose from various temperature reference settings (5°, 10°, 15°, 20°, 25°C), including linear and nonlinear options for advanced conductivity accuracy.
- Salinity readings can be based on practical salinity or natural seawater curves for precise results.
