The Best-Kept Secret in pH/ISE Measurement Its no mystery to analysts in the water/wastewater treat­ ment business—Hach's systems for electrochemical analysis are convenient, reliable and accurate.

You won't have to become a detective to learn more. Just contact Hach and ask for literature 3205.

Now the word is out to analysts in other fields about an advanced, versatile, application-oriented meter that provides: •Six operational modes—pH. ion concentration, mV, relative mV, incremental methods, temperature • Linear and true non-linear ISE calibrations • Double standard addition, standard and analyte addition/subtraction • Dual-measurement channels •Computer interface • Programmable stability indicator Complete analysis packages are available for measuring pH.
