pH meters

Introduction to pH meters

A pH meter is an analytical instrument used to determine hydrogen ion concentration, indicating the acidity or alkalinity of a solution in laboratory applications and water monitoring. Belonging to the multiparameter water testing instrument category, many modern pH meter series are also designed to expand testing to multiple physicochemical parameters on the same unit.

When selecting a laboratory pH meter, users should consider channel configurations such as single-channel or dual-channel with galvanic isolation depending on operational needs. Other important criteria include the ability to expand analysis to parameters such as ORP, mV, conductivity, dissolved oxygen, turbidity, or ion-selective electrodes, along with integration of IDS digital sensor technology. Hoa Viet currently supplies digital benchtop pH meters from the German brand WTW, meeting rigorous laboratory measurement standards.

Which brands of pH meters does Hoa Viet provide?

Hoa Viet currently supplies digital benchtop pH meters from the WTW brand (Germany).

Should I choose a single-channel or dual-independent-channel pH meter?

Single-channel meters are suitable for sequential analysis of individual basic parameters. Meanwhile, dual-galvanically-isolated-channel meters effectively meet the need for simultaneous measurement of two parameters, saving operational time.

Besides pH, which parameters can a multiparameter pH meter measure?

Depending on the model and compatible sensor, the instrument can support additional determination of ORP, mV, conductivity, dissolved oxygen, turbidity, and ion-selective parameters.

What should be noted when storing pH electrodes?

After each measurement, rinse the electrode thoroughly with distilled water and immerse it in the appropriate storage solution according to the user manual; never allow the sensing membrane to dry out.
