Mercad Equipment Inc

Improved Reference Electrodes For Sulphuric Acid Coolers

There are several different types of reference electrodes on the market for the anodic protection of acid coolers, storage tanks and piping. All of these electrodes have some shortcomings from the user’s point of view. They leak, brake easily, and are incompatible with some equipment or are simply overpriced.


Mercad Equipment Inc. manufactures a superior product and supplies an electrode that solves many all of these problems.


Compare these excellent features:


  • Heavy duty and hardened, pure (99.9%) platinum element to minimize possible damage from the acid flow.


  • Platinum-to-wire connection is located inside the electrode insulator to prevent bending and possible breakage of the Pt element.


  • Silver-soldered ground wire connection to the body ensures proper signal sensing.


  • The gland nut seal is pre-torqued under operating temperature (100+ degrees C) to ensure a proper acid seal and thereby prevent leakage. No adjustment of the seal nut is required for installation. However, the unit is still serviceable.


  • Universal electrode for Chemetics, Monsanto and NORAM acid coolers, storage tanks or acid piping.


  • Readily available at very competitive prices.


These improved reference electrodes from Mercad Equipment Inc. will reduce the need for frequent replacements thus providing substantial maintenance cost savings and reduced inventory need.
