Ion meter pX-150.2MI Sodium analyzer

Ion meter pX-150.2MI Sodium analyzer Designed for express control of the activity and concentration of sodium ions in demineralized water or aqueous solutions in water treatment plants and technological equipment of power plants and other industries. It can be used in workshop and laboratory conditions of power plants and boiler houses, both in the sampling system and as a control device when commissioning and periodically checking stationary sodium analyzers. Requirements for the analyzed environment: - aqueous solutions of inorganic and organic compounds; - technological solutions that do not form films and deposits on the surface of the electrodes; - fire and explosion proof. Features and Benefits: The microprocessor sodium analyzer has no mechanical controls, which eliminates the possibility of accidental settings failure; made in a dust- and moisture-proof housing, which allows it to be used in workshop conditions; easy to use, works in interactive mode using operator prompts; automatic diagnostics of electrode system parameters; the use of interchangeable temperature sensors allows you to avoid adjustments when replacing them; the setup results are saved in non-volatile memory; control of the pH value of the analyzed medium and temperature is provided with the display of readings; allows you to store 30 results in memory and stop the measurement process while maintaining the current readings on the display.
