A151 Benchtop Conductivity/TDS/Salinity/Resistivity Meter
• 1 to 3 points calibration with automatic recognition for conductivity standards.
• Selectable cell constant, reference temperature, TDS factor, linear/non-linear/pure water compensations, percentage/seawater/practical salinity measurement modes.
• Automatic temperature compensation corrects conductivity measurment to reference temperature.
• Auto-Read function senses and locks the measurement endpoint.
• Timed Interval Readings sends the measurement data to a PC or printer.
• Limit Alarm automatically alerts when reading exceeds the specified range.
• Calibration due alarm prompts user to calibrate the meter regularly.
• Calibration report 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.
