Will be discontinued Jan 1, 2020. Recommended replacement Lab Room Controller (LRC).","The TSI SureFlow™ Adaptive Offset Controller Model 8682 is an excellent laboratory pressure controller, designed to maintain more exhaust from a laboratory than is supplied to it. This negative air balance helps ensure that chemical vapors cannot diffuse outside the laboratory, complying with requirements in NFPA 45-2000 and ANSI Z9.5-2003.","The SureFlow Model 8682 also controls the temperature of the laboratory space by modulating reheat and the supply air volume. Optionally, a room pressure sensor can be connected to the SureFlow Model 8681 controller to correct long-term changes in the building dynamics.","The Model 8682 easily integrates to the building management system using either alarm relays or digital communications. The Model 8682 supports the open Modbus® protocol.","Applications","Included Items","Features & Benefits
