Salinity Meters

A150 Laboratory Conductivity/TDS/Salinity/Conductivity Ash Meter

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

Features:
• 1 to 3 points calibration with automatic recognition for conductivity standards.
• Selectable cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS factor (0.1 to 1),
  linear/non-linear/pure water compensations, percentage/seawater/practical salinity
  measurement modes, conductivity ash methods.
• Automatic temperature compensation corrects conductivity measurements to the reference
  temperature.
• Auto-read function senses and locks the measurement endpoint.

Laboratory Salinity Meter

• Timed interval readings send measurement data to a PC or printer.
• Limit alarm automatically alerts when measurements exceed the specified range.
• Calibration due alarm reminds user to calibrate the meter regularly.
• Calibration log shows the date, time, calibration points and factors.
• Password protection prevents unauthorized calibration and settings.
• Expanded memory stores or recalls up to 1000 data sets.
• Reset function automatically restores all settings to the factory defaults.
