Product Description

540 Portable Conductivity/TDS/Salinity Meter

Professional portable salinity meter contains the conductivity, TDS and resistivity measurement modes, setup menu contains 11 options, accuracy: 1% F.S.

Features:
• Professional portable salinity meter is equipped with a backlit LCD display.
• 1 to 5 points calibration with automatic recognition for conductivity standards.
• Selectable cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS factor, linear
  and pure water compensations, seawater and practical salinity measurement modes.



• Automatic temperature compensation corrects conductivity measurment to reference
  temperature.
• Auto-Read function senses and locks the measurement endpoint.
• Calibration due alarm prompts user to calibrate the meter regularly.
• Calibration report shows the calibration point and factor.
• Auto-Power Off effectively conserves battery life.
• Setup menu allows setting the number of calibration points, stability criteria, temperature
  unit, date and time, etc.
• Reset function automatically resumes all settings back to the factory defaults.



• Expanded memory stores or recalls up to 500 data sets.
• USB communication interface is easy to transfer data to PC.
• Multi-mode power scheme (batteries, power adapter and USB port) ensures that using the
  meter smoothly.
