Ensure the excellence of your vacuum sensors: With our customized residual gas analysis, we offer in-depth testing in pressure ranges from 1 × 10⁻⁴ to 1 × 10⁻⁸ mbar – reliable, fast, and precise.
At IFW Dresden, we inspect your components and external chambers with our in-house testing facility using high-precision residual gas analysis . In the relevant pressure range from 1 × 10⁻⁴ to 1 × 10⁻⁸ mbar, we reliably assess leaks, gas purity, and system integrity. Digital viscosity vacuum measurement (spinning rotor principle) enables particularly sensitive and stable detection—ideal for the calibration and certification of vacuum sensors.
Your benefits
- High pressure spectrum up to fine vacuum measurement
- Reliable residual gas analysis for quality control
- Robust, calibratable technology as a transfer standard
- Comprehensive service from testing to expert opinions
- Ideal for sensor manufacturers and users in research and industry
Methods
Digital viscosity vacuum measurement (spinning rotor gauge): A rotating steel ball is magnetically levitated, and its deceleration (due to molecular momentum loss) is used to determine the pressure – routine range: approximately 5 × 10⁻⁷ to 1 mbar. This method also serves as a reference standard for calibration purposes.
Fields of application
- Physical calibration and performance testing of vacuum sensors
- Validation of vacuum components in research and manufacturing
- Quality assurance of vacuum systems in analytics, semiconductor, pharmaceutical or aerospace industries
- Long-term tests for system integrity and leakage rate
