Description

Overview

GAOTek Water Quality Meter with 12 Multiparameter (Data Storage) is suitable for measuring the pH, mV, Conductivity and TDS of liquids. In the Conductivity/TDS mode the instrument features 1 to 5 points push-button calibration with automatic calibration solution recognition, selectable cell constant (0.1/1/10), normalization temperature, TDS conversion factor and linear or pure water compensation mode. System menu allows setting the 12 parameters, including the number of calibration points, resolution, stability condition, measurement unit, etc. Stored data can be transferred into computer by USB communication interface.

 

Key Features

  • Equipped with a large backlit LCD display
  • In pH mode, Ito 5 points push-button calibration with auto-buffer recognition and in conductivity/TDS Mode 1 to 5 points push-button calibration with automatic calibration solution recognition
  • Automatic electrode slope display helps user decide whether to replace sensor
  • Selectable cell constant (0.1/1/10), normalization temperature 68 °F/77 °F (20 °c /25°C), TDS conversion factor and linear or pure water compensation mode.
  • 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 is an operational guide that helps user quickly begin using the meter
  • System menu allows setting the 12 parameters, including the number of calibration points, resolution, stability condition, measurement unit, etc
  • Reset feature automatically resumes all parameters back to factory default settings
  • 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.
