pH and Conductivity Meter

pH and conductivity are key parameters used to measure the pH of a substance when evaluating nutrient, salt or impurity levels. pH and conductivity measurements are used in a variety of industries including industrial water and wastewater treatment, boiler maintenance and agriculture, and aquaculture and aquaculture The pH electrode consists of a reference electrode, a reference solution, a reference water contact, and a glass bulb with a hydrated gel layer. Once the electrode is inserted into the sample, a current is induced and the charge of the reference solution inside the bulb is measured against that outside the gel layer The result is a pH measurement. The conductivity between two or four electrodes is measured by the current method or potentiometry. When the electrodes are immersed in the sample, the electrodes flow through the sample solution. The number of ions in the solution will determine the conductivity or resistance of the sample. Conductivity is expressed in Siemens units. 2 Electrical probes (amperometers) – They work using two electrodes isolated from each other. They are made of non-reactive materials and designed so that both affect the sample simultaneously. These 2 electrodes pass a current via the sample at a certain frequency, the higher the ions, the higher the EC reading. 4 Potentiometer – The electrode body has four platinum rings. The upper and lower rings (outside) apply AC voltage to the sample and sense current. The middle ring (inserted into the top and bottom rings) measures the potential drop in current induced by the outer electrode giving a conductance reading.

The Key Features of pH and Conductivity Meter are as follows :

• Two activities
• A complete reading
• multi-parameter performance
• Thermal Compensation (ATC) 1.1.
• measurement and data entry
