THERE'S A BECKMAN p H INSTRUMENT FOR EVERY NEED
È M î®r
PROFIT-MINDED EXECUTIVE
COMPLETELY A U T O M A T I C ! The Beckman Model R instrument operates directly from standard 110 v. A.C. lines to provide com pletely automatic pH indication. Also provides for completely automatic pH recording and automatic process control. Can be installed to give accurate pH readings from various stations i n plant through one instrument. This is the pH unit being installed by today's most modern plants, large and small.
W W H ETHER you are an executive responsible for planning long-range plant production, • " or for obtaining maximum efficiency from present processing operations, one of the most important advancements you can make is the installation of BECKMAN pH CONTROL. Through the proper application of modern pH control you can make many vital savings . . . savings that will quickly pay for the installation and will continue paying big dividends throughout the years. For example, some of the many benefits resulting from Beckman pH Control include . , . . . . saving valuable chemicals through more accurate control of dosages. . . . reducing costly corrosion by prc-regulating acid and alkaline solutions. . . . speeding up process operations by operating at optimum pH values. . . . minimizing rejects by increasing the uniformity of process solutions. . . . and many other important savings in time, materials and plant operating costs.
PORTABLE A . C OPERATION! The Beckman Model Η instrument can be quickly moved from one part of the plant to another and plugs directly into standard 110 v. 5 0 / 6 0 cycle A.C. current. Compact, convenient and extremely simple to operate, the Model Η gives instant pH readings on an easily-read dial. It is widely used both for manual pH control of small plants and as an auxiliary instrument on completely automatic pH installations.
y BUT TO MAKE CERTAIN you get the Ic itest, most convenient and most occurate pH equipment available, be sure to specify "BECKMAN"...

T h e accuracy of Beckman p H readings is completely unaffected by human errors in color judgment, by turbidity, o x i d i z i n g o r reducing agents, by suspended materials, col ored process solutions or other vari ables that affect outmoded colorimetric methods. Beckman pH readings are universally accurate and dependable!

COMPLETELY SELF-CONTAINED! The Beck man Model M is the ideal pH instrument where complete portability is desired. Operating from its own self-contained, long-life power supply, the Model M can be used anywhere in the plant or field, whether convenient to power lines or not. Features the same accuracy, simplicity and operating speed as the Model H, and is also widely used both for manual pH control of small plants and as auxiliary equipment on large automatic installations.
