The precision and longevity of conductivity probe are excellent in normal conditions of lactic acid production by fermentation process. Strong acids have an extremely high concentration of hydrogen ions. The increase in lactate production is usually caused by impaired tissue oxygenation, either from decreased oxygen delivery or a defect in mitochondrial oxygen utilization. Lactic acid is a substance made by muscle tissue and by red blood cells, which carry oxygen from your lungs to other parts of your body.
