Description
Pfeiffer PTR26504 Vacuum Module IMR 265 PT120115-T Sensor KF Quick Flange
The Pfeiffer PTR26504 is a compact vacuum gauge module pairing the IMR 265 combination sensor with an integrated electronics housing and a KF (ISO-KF quick flange) vacuum interface. The IMR 265 sensor combines a Pirani thermal conductivity gauge for low-pressure measurement with an atmosphere reference detector, giving it a dual-range measurement capability switchable between P and HP modes directly on the module. The unit connects to a Pfeiffer vacuum gauge controller via its DIN-style signal connector and attached shielded cable.

Applications
The Pfeiffer IMR 265 combination vacuum sensor is used in research and industrial vacuum systems where pressure monitoring across both rough and fine vacuum ranges is needed from a single compact unit. It is commonly found on vacuum deposition chambers, load-lock systems, and foreline connections in semiconductor process equipment, as well as in university research labs, thin-film coating systems, and general vacuum R&D setups. The KF quick-flange interface is the standard low-to-medium vacuum connection found on the majority of vacuum chambers and forelines, making this module compatible with a wide range of existing vacuum hardware. The module connects to Pfeiffer's TPG series gauge controllers and compatible multi-channel vacuum measurement systems.
This Pfeiffer PTR26504 Vacuum Module with IMR 265 sensor (PT120115-T) has been visually inspected and appears to be in good used condition. The housing shows general surface soiling and light scuffing consistent with lab use; a red marking is visible on the side panel. The KF quick flange, stainless steel sensor stem, and DIN signal connector are all intact. The attached Belden 8723 shielded cable is complete. We were unable to power or test this unit at our facility, so it is sold as-inspected with no functionality guarantee. Please view our photo set and contact us if you have any questions.
