Key Instruments unveiled the Series 8500 Optaflow Controller for liquid and gas fluid control in R&D analysis, pilot plant, small batch and quality assurance applications. Engineered to provide up to +/- 3 percent of full scale standard (+/- 1 percent optional), the Series 8500 Optaflow Controller combines non-contact optical sensors and electromechanical features to set and monitor flow control functions.
Liquid models are calibrated for water and contain a manual bleed valve. Gas models offer selectable calibration of six gases: air, O2, N2, Ar, CO2 and HE. Key Instruments; Tel: (800) 356-7483; Fax (215) 357-9239; Email: email@example.com; www.keyinstruments.com
