Hi-2621 pH and Orp Benchtop Meter with Data Logging
The HI-2621 benchtop meter is a fast, accurate pH and ORP meter with probes for pH and Orp. The sensors measure the parameter together with the temperature.
Simply and easy to use : Configuration, calibration, measurement and data logging.
Useful for routine applications together with a Standard Operating Mode, enabling all features and capabilities.
The HI-2621 meter has a large display - 5.5” (14 cm) LCD.
Main feature points
- Automatic parameter recognition
- pH/ORP choice of measurement units: pH, mV;
- CAL Check indicators
- Sensor Check indicators
- Basic mode for simplified operation
- Dedicated GLP key
- GLP data included with logged data
- Simplified data transfer to a PC
- Internal clock and date
Key Features
- Digital probe input
- Two operating modes - Standard or Basic Operating Modes (pH and EC only). Standard Mode enables all features while Basic Mode displays a simplified screen and features
- Data storage up to 1000 log records.
- GLP - The sensor retains data from the most recent calibration, including date, time, and buffers utilised.
- CAL Check - CAL Check feature analyses the pH electrode’s response in calibration buffers to detect potential issues such as contaminated solutions or dirty electrodes.
- ORP measurement - Measure ORP (REDOX) in mV units by using a compatible ORP sensor.
