The NastyBoy, MEECO's new on-line analyzer for moisture in chlorine, stands up to the toughest applications. Combining durabiliy and accuracy, the NastyBoy features an advanced flow system design, using corrosion-resistant materials throughout. The unit functions as a 24VDC, two-wire transmitter, with exceptional mounting flexibility and low installation costs.
A dual NEMA 4X enclosure assembly isolates the electronics from the flow system. Inert gas purge ports prevent build up of hazardous, corrosive gases. Best of all, NastyBoy's field-proven, electrolytic technology provides accurate and reliable measurement -- without field calibration. Based on Faraday's Law of Electrolysis, the NastyBoy's sensor absorbs and electrolyzes moisture down to fractional parts-per-million (ppm's).
One hundred percent of the sample moisture is absorbed by a phosphorus pentoxide film that covers two spirally wound electrodes. By applying an electrical potential (voltage) to the electrodes, each absorbed water molecule electrolyzes, generating a finite current. This current is precise and proportional to the amount of absorbed water. It is, therefore, an exact direct measure of the water vapor present in the sample gas. That's why the electrolytic cell requires no calibration and is specific to water.
