Benchtop Multiparameter Water Quality Meter
High accuracy multiparameter water quality meter includes 15 optional parameters, the meter is suitable for measuring the pH, ORP, Ion concentration, Conductivity, TDS, Salinity, Resistivity and Dissolved Oxygen of the liquids.
pH Mode:
• High accuracy benchtop multiparameter water quality meter is equipped with a large backlitLCD 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 a 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.
