Description
1, Product Introduction
High-precision laboratory conductivity meter, suitable for measuring conductivity, TDS, salinity, resistivity and conductivity ash, 1 to 3 points calibration, accuracy: 0.5% F.S.
2, Features
• High-precision laboratory conductivity meter is equipped with a 7 inch TFT display.
• 1 to 3 points calibration with automatic recognition for conductivity standards.
• Selectable conductivity ash, cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS conversion factor, linear/non-linear/pure water compensations,percentage/seawater/practical salinity measurement modes.
• Automatic temperature compensation corrects conductivity measurements to the reference temperature.
• Auto-read function senses and locks the measurement endpoint.
• Timed interval readings send the measurement data to a PC or printer.
• Limit Alarm automatically alerts when reading exceeds the specified range.
• Calibration due alarm reminds the user to calibrate the meter regularly.
• Calibration log shows the date, time, calibration point and factor.
• Password protection prevents the unauthorized calibration and settings.
• Expanded memory stores or recalls up to 1000 data sets.
• Reset function automatically resumes all settings back to the factory defaults.
