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 user decide whether to replace 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.

Ion Mode:

  • 2 to 5 points calibration including the eight concentration calibration points can be selected.
  • Automatically recognize ion selective electrodes, does not need to specify type of ion.
  • Direct ion concentration readout simplifies the elaborate measurement process.
  • Selectable multiple concentration units including the ppm, mg/L and mol/L.

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.

Dissolved Oxygen Mode:

  • 1 or 2 points calibration using air-saturated water and zero oxygen solution.
  • Manual salinity and barometric pressure compensation improve the measurement accuracy.

Other Features:

  • Automatic temperature compensation provides accurate reading over the entire range.
  • Calibration due reminder prompts user to calibrate the meter regularly.
  • Stability indicator automatically shows 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 allows setting the 15 parameters, including the calibration points, resolutions, stability conditions, measurement units, etc.
  • Reset feature automatically resumes all parameters back to factory default options.
  • Expanded memory stores and recalls up to 500 readings.
  • Built-in real-time clock stamps stored data to meet GLP standard.
  • 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.
  • Supplied with buffers, probes and a tough carry case.
