The Pfeiffer Vacuum IMR 265 is a compact process ion gauge designed for accurate vacuum measurement across a wide pressure range. By combining Pirani and hot cathode sensors, it ensures precise monitoring from high to ultra-high vacuum levels. The device intelligently controls the activation of the hot cathode sensor based on pressure thresholds to extend filament life and enhance measurement reliability. Its corrosion-resistant construction and compatibility with various control units make it a versatile choice for diverse vacuum applications.​

Key Features:

  • Dual Sensor Design: Integrates both Pirani and hot cathode sensors within a single compact unit, providing a broad measurement range from 2Ɨ10⁻⁶ hPa to 1000 hPa.​
  • Automatic Sensor Control: The hot cathode sensor is activated only below a user-defined pressure threshold (factory set at 5Ɨ10⁻² hPa) to prevent filament burnout, while the Pirani sensor monitors higher pressures.​
  • High Measurement Accuracy: Offers precise pressure readings across its entire range, suitable for various vacuum applications.​
  • Corrosion-Resistant Construction: Built with materials resistant to corrosion, ensuring durability and reliability in demanding environments.​
  • Compact and Versatile: Its design allows for easy integration into existing systems, compatible with Pfeiffer Vacuum measurement and control units or other control devices.​
  • User-Adjustable Thresholds: Features five definable switching thresholds for the hot cathode activation, allowing customization based on specific process requirements.​
