Announcing the n e w CORNING" Model 1 2 p H Meter Read about the remarkable new precision, versatility and reliability it brings into your lab at a surprisingly low price Precision—reproducibility t o ± 0.002 pH or ±0.20 millivolt on a full, 7inch scale deflection of any 1 p H unit or any 100 mv range.

All our electrodes are ruggedly made. Model 12 accessory kit—included are a Triple-Purpose electrode for p H measurements from 0-14, a calomel reference electrode with fiber junc­ tion, electrode support and clamp, saturated KC1 and a buffer solution, an adapter plug, and an instru­ ment cover.

Versatility—its expandable scale al­ lows you to calibrate on one range and read on others without recalibration; utilize automatic temperature compensation, make oxidation-reduc­ tion measurements and Karl Fischer titrations.

Price—$495, sory kit.

Reliability—the critical circuits in the Model 12 use ± 1 % tolerance components made by our Electronics Division, supplier to t h e nation's space/missile industry. These com­ ponents drift less than 0 . 1 % per year to insure stable operation. CORNING®
