About Arizona Instrument

Established in 1981, Arizona Instrument is an ISO 9001:2000 registered company that designs, manufactures, and markets Computrac® precision moisture analysis instruments and portable and fixed Jerome® toxic gas analyzers used in research and development, quality control, and process control applications. The company is well established across all industries, including plastics, foods, chemicals, pharmaceuticals, forestry, paints and coatings, pulp and paper, mercury and hydrogen sulfide. We provide complete pre- and post-sale customer service including application development, training, and instrument calibration and repair.

The Computrac® Vapor Pro® series detects moisture levels as low as 10 ppm, or 10 ug, in samples as small as 10 mg utilizing moisture-specific sensors to eliminate volatile interferences. The Computrac® MAX® series measures moisture content as low as 0.005 percent in as few as 3 minutes. These instruments are durable, easy to use, and equally suitable for the production floor and the laboratory.

Utilizing patented gold sensor technology, the Jerome® 631-X measures hydrogen sulfide concentrations of 3ppb to 50ppm, while the Jerome® 431-X mercury vapor analyzer detects concentrations from 0.003 to 0.999mg/m3, all in just 13 seconds. The Jerome® 860 hydrogen sulfide monitor provides automatic, unattended, long-term monitoring of hydrogen sulfide gases in contained or hard to reach areas. The compact, battery powered 860 is water resistant and intrinsically safe. Accessories include a field test kit for easy verification of instrument calibration, a data logger for data acquisition and instrument programming, and software for connecting the analyzers to computers.
