WD-35433-71 CD 650 Portable Waterproof Conductivity / Dissolved Oxygen Meter with Kit, with NIST Traceable Certificate of Calibration by Oakton
Great for salt water testing!
- Durable waterproof and dustproof design with IP67 rating – Even with no probes attached
- Push-button calibration for all parameters – 5 points for conductivity; 3 points for DO
- Large backlit graphic display – Multiline display with electrode status indicator, calibration data, and more
- User-settable “calibration due” alarm – Out-of-date or unperformed calibrations are now things of the past!
- Built-in real-time clock – Time-and-date stamping meets Good Laboratory Practice (GLP) standards
- Store up to 500 data sets – Infrared IrDA wireless technology makes PC downloading convenient and easy
- Set point alarms – Audible warning when readings are outside set points limit
- Research-grade accuracy – Resolution to 0.001 pH and accuracy to ±0.002 pH
- Electrode status indicator – Calibration data provides electrode diagnostic tool
- Password protection – Security for calibration and setup menus
- Rugged rubber boot – Protects meter from impact (optional; included with kit)
