Pellet moisture analyzers that employ relative-humidity sensing technology are now approved under a new standard adopted by Philadelphia-based ASTM in late 2005. That's the word from Arizona Instruments LLC, Tempe, Ariz., whose Computrac Vapor Pro is an example of this type of instrument, which provides fast, safe, and cost-effective moisture analysis. ASTM approval and standardization of this test method helps processors who use it for quality control, especially if they ever become involved in product-liability issues. Prior to adoption of ASTM D7191-05, "Standard Test Method for Determination of Moisture in Plastics by Relative Humidity Sensor," Karl Fisher "wet" titration was the only approved method for moisture specific testing of plastics. The latter requires extensive training, expensive glassware, and ongoing costs for chemical reagents and disposal fees. Relative-humidity instruments eliminate all those concerns and are usable both on the production floor and in the laboratory. Arizona Instruments: (602) 470-1414 . PTDirect: 943XV
