KJ-531 Portable Conductivity/Salinity Meter

·Product discription
High accuracy portable Conductivity/Salinity meter, 5 points calibration, selectable seawater and practical salinity measurement modes. The meter contains 10 optional parameters. Accuracy: 1% F.S.

1. High accuracy portable salinity meter contains conductivity measurement mode.
2. 1 to 5 points push-button calibration with automatic calibration solution recognition.
3. Selectable cell constant (0.1/1/10), normalization temperature, linear and pure water
  compensation modes, seawater and practical salinity measurement modes.
4. Automatic Temperature Compensation provides accurate reading over the entire range.
5. Calibration Due Reminder prompts user to calibrate the meter regularly.
6. Stability indicator automatically shows current measurement status.
7. Auto-Hold function freezes stable measured value for easy viewing and recording.

8. Selectable temperature unit (°C or °F) meets different application requirements.
9. Automatic electrode diagnosis shows cell constant of the sensor.
10. Help message as a operational guide that helps you quickly begin using the meter.
11. System menu allows setting the 10 parameters, including the number of calibration points,
  stability condition, temperature unit, hold function, etc.
12. Reset feature automatically resumes all parameters back to factory default settings.
13. Expanded memory stores and recalls up to 500 readings.
14. Built-in real-time clock stamps stored data to meet GLP standard.
15. Stored data can be transferred into computer by USB communication interface.
16. Multi-mode power scheme (battery, power adapter, computer's USB port) ensures that use
