The MEWOI-96031 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 or user could attach three kinds of probes at the same time. So the MEWOI-96031 Multiple Parameters Water Testers could be operated as the pH meter, conductivity meter, TDS meter, Salinity meter or D.O. meter as user needed. 
We design different color connector on the meter, user only needs to screw on the probe with the same color, and then get the measuring reading accurate and fast. 
User could change the probe or screw on the MEWOI-96031 Combo 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 MEWOI-96031 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.
