Product Description

pH / mV / ORP / Conductivity / TDS / Salinity / Resistivity/C - (LCD Display)


Presto is best known for producing the world-class, high-quality testing instruments all over the world. We research and experiment the new devices that can check the each corner of the material to prevent even the minor flaws. We are introducing highly accurate benchtop multiparameter water quality meter equipped with a large backlit LCD display. Our device has three modes; pH modes, ORP mode, and Conductivity/TDS/Salinity/Resistivity Mode.

Key Features

pH mode

  • Equipped with a large backlit LCD display.

  • One to five push button calibration that have auto-buffer recognition.

  • Selectable pH buffer standards (USA/NIST/DIN) provided with custom calibration solutions.

  • Sensor replacement can be determined with the help of automatic electrode slope display.

ORP mode

  • A single point offset calibration is available to adjust a known standard.

  • The relative and absolute millivolt measurement modes with accurate ORP readings.

Conductivity/TDS/Salinity/Resistivity Mode

  • One to five points push-button calibration with auto-buffer recognition.

  • Selectable cell constants (0.1/1/10), normalization temperatures 20/25 degree Celsius, TDS conversion factors, seawater and practical salinity measurement modes are available

  • Meter accuracy is improved by a liner or pure water compensation.

Additional Features

  • With Automatic Temperature Compensation, accurate reading is provided over the entire range.

  • Regular meter calibration is prompted with Calibration Due Reminder.

  • The current measurement status is indicated through Stability Indicator.

  • Easy view and record with an Auto-Hold function that freezes the measured value.

  • Temperature deviation is corrected by manual temperature calibration.

  • Different applications requirements are fulfilled by selectable temperature unit (°C or °F).

  • By automatic electrode diagnosis, zero point offset and slope of the electrode are indicated.

  • Help message guides for immediate beginning with a meter.

  • The 12 parameters setting is enabled on the system menu, including the calibration points, resolutions, stability conditions, measurement units, etc.

  • All parameters can be set back to factory default option with reset feature.

  • The tool has expanded memory that is efficient to store and recall up to 500 readings.

  • Data is stored to meet GLP standard with built-in real-time clock stamps and then transferred to the computer through the USB communication Interface.
