SciQuip Portable pH/ORP/Conductivity/TDS/ Salinity/°C/°F Meter

High accuracy multiparameter water quality meter includes 6 measurement modes, the meter is suitable for measuring the pH, ORP, Conductivity, TDS, Salinity and Resistivity of the liquids.

pH Mode:

  • High accuracy portable multiparameter water quality meter is equipped with a large backlit LCD display.
  • 1 to 5 points push-button calibration with auto-buffer recognition.
  • Selectable pH buffer standards (USA/NIST/DIN) or using the custom calibration solutions.
  • Automatic electrode slope display helps the user decide whether to replace the sensor.

ORP Mode:

  • Single point offset calibration allows adjusting the displayed value to a known standard.
  • Relative and absolute millivolt measurement modes provide accurate ORP readings.

Conductivity/TDS/Salinity/Resistivity Mode:

  • 1 to 5 points push-button calibration with automatic calibration solution recognition.
  • Selectable cell constants (0.1/1/10), normalization temperatures (20/25°C), TDS conversion factors, seawater and practical salinity measurement modes.
  • Linear or pure water compensation improves the measurement accuracy of the meter.

Other Features:

  • Automatic Temperature Compensation provides accurate reading over the entire range.
  • Calibration Due Reminder prompts the user to calibrate the meter regularly.
  • Stability indicator automatically shows the current measurement status.
  • Auto-Hold function freezes stable measured value for easy viewing and recording.
  • Manual temperature calibration corrects temperature deviation.
  • Selectable temperature unit (°C or °F) meets different application requirements.
  • Automatic electrode diagnosis shows zero-point offset and slope of the electrode.
  • Help message as an operational guide that helps you quickly begin using the meter.
  • System Menu controlling 11 parameters, including the number of calibration points, stability conditions, Temperature units, hold function, date, time etc.
  • Reset feature automatically resumes all parameters back to factory default options.
  • Expanded memory stores and recalls up to 500 readings.
  • Stored data can be transferred into computer by USB communication interface.
  • Multi-mode power scheme (battery, power adapter, computer’s USB port) ensures that use the meter smoothly.
