Arizona Instrument Corp. designs and manufactures precision instruments used in quality control, industrial control and environmental monitoring applications. The Company initial product was the Computrac moisture analyzer for use in process control industries. Arizona has expanded its operations to include the production of the Jerome line of mercury and hydrogen sulfide gas analyzers for use in industrial hygiene, industrial process quality control, and mercury dental amalgam screening applications. In addition, in 1994 Arizona introduced the Encompass product, its next generation of fuel management and leak detection compliance systems. In response to the declining sales of Encompass and Sentry products, the Company sold certain assets related to the Encompass and Soil Sentry segment to National Environmental Service, Co.
