Water Quality Tester

Multi-Parameter Water Quality Tester

water quality testerHand held instrument for the measurement of six different water quality parameters; pH, Conductivity, Salinity, Dissolved Oxygen, Temperature and Turbidity.
All of the six sensors are enclosed inside one probe which can be directly submersed in a river well or, other water source with no sample collecting required.

  • Simultaneously measures pH, Conductivity Salinity, Dissolved Oxygen, Temperature and Turbidity
  • Automatic temperature compensation for pH, conductivity and dissolved oxygen
  • Internal memory for storage of up to 20 samples with recall display and printout functions
  • Expanded display function allows an increase in resolution by one decimal place when more precise measurements are required
  • One touch, push button automatic calibration, alternatively, manual two point calibration can be carried out if required
  • Rugged construction with water resistant housing
  • Data back-up function
  • LCD display
  • Battery powered (1 X 9V), approximate battery life 750 hours
  • Automatic power off
