AZ-86031 5 in 1 Water Quality Meter Dissolved Oxygen Tester PH Meter PH Conductivity Salinity Temperature Meter AZ86031

The 86031 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 86031 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 86031 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 86031 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..

RCYAGO Dissolved Oxygen Meter with Electrode Filling Fluid

Dissolved oxygen meter is a precision instrument for measuring dissolved oxygen and temperature. The dissolved oxygen probe is a thin film with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode but allows oxygen to pass through the membrane to react, and the concentration can be measured..
Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, generally expressed in mg/L (ppm) and saturation percentage (%), which is the percentage of dissolved oxygen in 1L of water. The oxygen concentration of our dissolved oxygen meter is 0.0-40.0mg/L, most of the range of dissolved oxygen meters on the market is 0.0-20mg/L. When measuring and calibrating, needn't open the protective cover of the electrode, just put the electrode in the solution for measurement..
Detachable probe, easy to replace, equipped with 6 probe protective covers and anaerobic water calibration powder. The film inside the protective cover cannot be taken apart. After using it for a period of time, the test value is inaccurate and the calibration is still inaccurate, and the membrane sleeve needs to be replaced..
