Portable Multiparameter Water Quality Meter

Portable Multiparameter Water Quality Meter

High performance multiparameter water quality meter contains the 8 measurement modes. The meter is suitable for measuring the pH, ORP, ion concentration, conductivity, TDS, salinity, resistivity and dissolved oxygen of the samples.

pH Mode:
• 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 group (USA/NIST/DIN) or using the custom calibration solutions.
• Automatic electrode slope display helps user decide whether to replace the pH electrode.

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

Ion Mode:
• 2 to 5 points calibration including the eight concentration calibration points can be selected.
• Automatically recognizes the ion selective electrode, 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, automatically recognizes the standard solutions.
• Linear and pure water compensations improve the measurement accuracy of meter.
• Selectable cell constant, normalization temperature, TDS conversion factor, seawater and
  practical salinity measurement modes.

Dissolved Oxygen Mode:
• 1 or 2 points calibration using the air-saturated water and zero oxygen solution.
• Manual salinity and barometric pressure compensations ensure accurate measurements. 


Other Features:
• Calibration Due Reminder prompts user to calibrate the meter regularly.
• Stability indicator automatically shows current measurement status.
• Auto-Hold function freezes stable reading for easy viewing and recording.
• Automatic Temperature Compensation provides accurate reading over the entire range.
• Manual temperature calibration corrects the 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 a operational guide that helps user quickly begin using the meter.
• System menu allows setting the 15 parameters, including the number of calibration points,
  resolution, stability condition, measurement unit, etc.
• Reset feature automatically resumes all settings 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.
