A150 Laboratory Conductivity/TDS/Salinity/Conductivity Ash Meter

High-precision TDS meter contains 5 measurement modes, the meter is suitable for measuring conductivity, total dissolved solids, salinity, resistivity and conductivity ash, accuracy: 1% F.S.

Features:
• 1 to 3 points calibration with automatic recognition for standard solutions.
• 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 measurements to the reference temperature.
• Auto-read function senses and locks the measurement endpoint.

Laboratory TDS Meter

• 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.
