WeVe lowered chloride detection to 10 parts per billion Our new Ultra Sensitive Chloride Electrode responds to chloride in the 10 parts per billion range, without compromising selectivity. A range 25 times lower than can be measured with conventional chloride electrodes! This revolutionary, new, solid-state electrode is a major break-through for industrial process applications demanding ultra-pure water, and for monitoring high purity water in steam boilers and conventional power generating stations. As such, it brings new sensitivity to direct chloride measurement in biological materials, foods, soils, insecticides, plating baths, potable water and

wastewater. . . without resorting to pre-concentration steps and expensive, highly complicated techniques. This latest electrode development is just one example of how much we care about your need for improved electrode performance. We're on your side! We also offer pH and ORP electrodes in conventional glass or break-proof polymer bodies, removable protective tips, renewable and porous Teflon junctions. More, we ship our electrodes in keep-fresh soaker bottles, ready for immediate use and for long shelf life. Should our electrode fail to operate properly, we've made it easy for you to return it. Just put it back in its own shipping carton, use our special "return" label, and mail. We'll ship a replacement within 24 hours. For more information, s e e your local GC representative.
