Application Combo Water Meter-pH / Conductivity / SALT / TDS / D.O:
The Combo Water Testing Meter can measure the pH, Conductivity or TDS or Salinity and Dissolved oxygen depend on which kind of probe attach to the meter. So the Multiple Parameters Water Testers could be operated as the pH meter, conductivity meter, TDS meter, Salinity meter or D.O. meter as user needed.

User could change the probe or screw on the NCombo Water Quality Measuring Instrument easily. And in order to avoid broken by the stone or particle attacking in the measuring environment, we have developed the specific anti-collision cap on each probe. So the  Combo Water Testing Meter would be the best tool for all professional measuring purposes, including the Aquaculture, Aqua farm, LAB, swimming pool or water treatment business, or other related industry, no matter the fresh or sea water.

The Water Meter-pH / Conductivity / SALT / TDS / D.O has the back light function, which could help user to operate the measurement in the dark area.
