Description
The YOKOGAWA K9634JF-03 is a high-precision Temperature Input Card specifically engineered for the Yokogawa GC1000 MK II Process Gas Chromatograph. This module is responsible for accurately acquiring temperature signals from the analytical oven, column heaters, and detector zones. It converts raw signals from thermocouples or RTDs into digital data that the chromatograph’s main controller uses to maintain the precise thermal profiles required for reliable chemical analysis.
