Portable Multiparameter Water Quality Meter | KS-MS-900P-DELUXE



The KS-MS-900P-DELUXE Multiparameter portable water quality meter includes the 8 measurement modes. The meter is suitable for measuring the pH, ORP, Ion concentration, Conductivity, TDS, Salinity, Resistivity and Dissolved Oxygen of the liquids.

Features:

pH

• 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 standard (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 includes the ppm, mg/L, mmol/L and mol/L.

Conductivity/TDS/Salinity/Resistivity Mode

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

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 number of calibration points,
  resolution, stability condition, 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.
