Combo Water Quality Tester

Sale priceR 2,346.67
SKU: VZ84051AZ0



Meter & Probe Type:Meter Only

The AZ 84051 Combo Water Meter can measure multiple parameters, namely pH conductivity, salinity, TDS, and dissolved oxygen by changing to the appropriate probe.

Highlighted Features

  •  Large LCD to display multiple parameters in turns:
    • pH
    • Conductivity or TDS or Salinity
    • Dissolved oxygen
    • Temperature (by using different probes)
  • The displayed parameter is decided by probe type
  • Green backlight for dark environment
  • Fast measuring of dissolved oxygen value
  • Accurate replaceable probes with anti-collision cap
  • Auto-ranging for conductivity measurement
  • Auto temperature compensation (ATC)
  • 99 points memories w/recall function
  • Multiple points calibration: 3 points for pH, 1 point for D.O., 4 points for conductivity
  • Manually altitude and salinity compensation function for D.O. measurement
  • Easy replacement probes
  • Temperature unit ℃/℉ is switchable
  • 1-hour auto power off
  • Excellent to use in fresh or seawater aqua farm


The 84051 Combo Water Testing Meter can measure the pH, Conductivity or TDS or Salinity, and Dissolved oxygen depending on which kind of probe is attached to the meter. So the 84051 Multiple Parameters Water Testers could be operated as the pH meter, conductivity meter, TDS meter, Salinity meter, or D.O. meter as user needed.

The user could change the probe or screw on the 84051 Combo Water Quality Measuring Instrument easily. And in order to avoid breaking by the stone or particle from attacking the measuring environment, we have developed a specific anti-collision cap on each probe. So the 84051 Combo Water Testing Meter would be the best tool for all professional measuring purposes, including the Aquaculture, Aquafarm, LAB, swimming pool or water treatment business, or other related industries, no matter the fresh or seawater.

The 84051 AZ Combo Water Meter-pH / Conductivity / SALT / TDS / D.O has a backlight function, which could help the user to operate the measurement in a dark area.
