Ultra-high sensitivity gyroscope leak detection equipment
This ultra-high sensitivity leak detection device achieves an ultra-low background in the leak detection chamber through a molecular pump. The suction pump removes residual hydrogen molecules from the chamber, while a quadrupole mass spectrometer detects all helium gas leaking from the workpiece, thereby enhancing the sensitivity of the gyroscope leak detection and improving the control accuracy of the gyroscope. The minimum detectable leak rate of this system can reach 1×10^-13 Pa·m³/s. This device is suitable for ultra-high sensitivity leak detection of small precision instruments such as gyroscopes and infrared detector dewars.

Product Details
Device Features
This ultra-high sensitivity leak detection device achieves ultra-high background levels in the leak detection chamber through a molecular pump. The suction pump removes hydrogen molecules remaining in the leak detection chamber, and the quadrupole mass spectrometer detects all helium gas leaking from the workpiece, improving the sensitivity of the gyroscope leak detection and thus enhancing the control accuracy of the gyroscope. The minimum detectable leak rate of this system can reach 1×10-13Pa·m3/s. This device is suitable for ultra-high sensitivity leak detection of small precision devices such as gyroscopes and infrared detector dewars.
