Chloride Detection Breakthrough
Today, chloride can be detected in concentrations of less than 10 PARTS PER BILLION without expensive equipment including refrigeration units or metering pumps. Our new Ultrasensitive Chloride Electrode responds to chloride below 10 ppb - and it's easy to use. Now, when you must dilute a sample to avoid fouling a reference electrode, you can still obtain a linear response with our unique, solid-state electrode. And, our selectivity is equal to or better than any other conventional electrode. We also offer other UltraSensitive Electrodes (Bro-
/
mide and Thiocyanate) a complete line of longlife Ion Selective Electrodes (I", CN~, S2-, Ag+, Cd2+, Cu2+, Pb2+, & Hg2+),
a wide line of pH and ORP Electrodes, (in highquality glass or breakproof polymer bodies), and easy to use, preassembled Gas Sensing Electrodes (NH 3 , C0 2 , NO x ). We're electrode SPECIALISTS - we provide you with full technical support, a broad line of sensing electrodes, meters, calibrating solutions, and other helpful accessories.
