Model 650 FID - High-Temperature Flame Ionization Sensor - Datasheet

The Model 650 FID is a high-temperature flame ionization sensor that continuously measures total hydrocarbon concentrations. Control Instruments` proprietary FID design assures an accurate and linear response. A carefully metered pilot flame incinerates the sample. The resulting ionized carbon passes through an electrical field, creating a proportional current flow. An electrometer measures the current flow. The resulting electrometer output is amplified and displayed as either: parts per million of a hydrocarbon (PPM); Milligrams of Carbon per Cubic Meter (mgC/m3); or PPM of Carbon by Volume (PPMCv).
