Multiparameter Water Quality Meter

Multiparameter Water Quality Meter

High accuracy multiparameter water quality meter contains 15 optional parameters, the meter is suitable for measuring the pH, ORP, ion concentration, conductivity, TDS, salinity, resistivity and dissolved oxygen of the samples.

pH Mode:
• 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.
