pHS-3C，3B，3D，3E pH meter is controlled by a microprocessor, which has blue back light and double digital display LCD; it has a function of displaying pH (mV) index and temperature index at the same time,
It is suitable for taking a sample and determining the index of acidity (pH) of the aqueous solution and measuring electric potential value (mV) of the industrial mining and laboratory of the institute.
With ORP electrode can measure ORP value of the solution. If attach ion selectivity electrode can detect it's electric potential.
