Description

Overview

GAOTek conductivity probe is an online water quality monitor with a microprocessor. It’s equipped with conductivity electrodes of different types and different constants for continuous monitoring and control of the conductivity and temperature of the aqueous solution. The meter adopts LCD display, intelligent Chinese menu operation; with current or voltage output, free setting of measurement range, high and low over-limit alarm prompt and three sets of relay control switches, adjustable hysteresis range; automatic or manual temperature compensation. According to user needs, the conductivity electrodes have various installation processes such as flow-through type, pipe type, submersible type, and flange type, etc. 

 

Features

  • Intelligence: Conductivity measurement, temperature measurement and compensation 
  • Man, machine dialogue: menu operation structure, user can operate according to the prompts on the screen 
  • Multi parameter display on the same screen: simultaneous display of conductivity value, temperature value and working status 
  • Two way current output 
  • The measurement range and the upper and lower alarm limits can be set freely; the alarm prompts when the upper and lower limits exceed 
  • Three groups of relay control, adjustable hysteresis control range 
  • Self-set password and service guide
