pH/Conductivity Analyzer Model 4403 offers pH measurements from 0 to 14, readable to two places, and five conductivity ranges between 0-1.4 and 0-140,000 Mohms/cm. Spe­ cific ion measurements (optional) may also be read either in millivolts or pH. Liquid crystal digital readout is fea­ tured. The 9 X 10 X 8-in. analyzer is available in 110 or 220-V 50/60-Hz models and is priced at $773. Markson Science, Inc. 404

Trace Analyses Electroanalytical System Model 174A/315 automated electroan­ alytical system is capable of providing part-per-billion analysis of metals, an­ ions, organics, pollutants, and phar­ maceuticals, utilizing a polarographic analyzer and automated electroanalysis controller. Automatic operation deaerates and blankets the sample so­ lution, preconditions the working elec­ trode, initiates and terminates the scan, times critical steps in the run, controls the stirrer, provides duplicate or triplicate runs, and controls strip chart advance. Priced at $4570. Princeton Applied Research Corp. 413
