Teledyne Hastings 045500100 Orifice Holder Assembly

The Teledyne API 045500100 Orifice Holder Assembly is a precision OEM internal pneumatic component that maintains a 4 mil (0.004 in.) critical gas flow restriction for stable sample flow and accurate measurements in Teledyne gas analyzers. It is designed for Teledyne T-Series, N-Series, and legacy 200 Series gas analyzers and supports applications in Continuous Emissions Monitoring Systems (CEMS), ambient air quality monitoring, and industrial process gas analysis. Maintenance technicians and system integrators use this assembly for repair, retrofit, replacement, and preventive maintenance of Teledyne instrumentation. Constructed as a precision-machined holder with a replaceable critical flow orifice, it is commonly replaced by TELEDYNE 045500300, 045500400, or 045500500 when performing service.
