2026 Hydrochloric Acid Analyzer

From Metrohm Process Analytics

Hydrochloric acid (HCl), also known as muriatic acid, is a highly corrosive basic chemical majorly formed as a co-product from various processes. It is also used as an acid etchant in surfac-ing industries (such as automotive, semiconductor, etc.) as well as in the production of an array of different products. Some of the main uses are in the production of chlorine gas (Cl ) and 2

polymers (such as polyvinyl chloride, or PVC), as a metal surface treatment (pickling), and of course as a process pH adjustment.

Because of its role in many different (production) processes, it is of vital importance to closely monitor the concentration. The 2026 Hydrochloric

Acid process analyzer from Metrohm Process Analytics is the most straightforward and easy-to-use tool to do so online.

About the Hydrochloric Acid application Hydrochloric acid is determined by titrating with sodium hydroxide (NaOH), or alternatively with sodium carbonate (Na CO ). The detection 2

is performed with a Metrohm pH glass electrode. The analyzer is able to handle a wide range of acid concentrations, from mg/L to %.
