  DUAL PARAMETER METERS           pH,mv,ms, s,mg/L,ppt,oC

pH/Conductivity Meter - CpHC

In some applications there may be a need to measure different parameters of a solution. The same can be fulfilled by using a single instrument with different electrodes for the respective parameter. A single instrument can measure simultaneously different combinations such as pH / Conductivity, pH/ Ion concentration, pH /Dissolved oxygen, Conductivity/Dissolved oxygen along with temperature. These instruments find usage in environmental protection, water quality checking, biological agriculture, aqua culture, scientific research and studies, etc.
