Agilent / Varian PHD-4 Sniffer

Agilent / (previously is Varian) PHD-4 Sniffer Helium Leak Detector

The Agilent / (previously is Varian) PHD-4 sniffer helium leak detector is able to detect very small leaks in objects that have a slight helium/air pressure inside. The lightweight and rugged sniffer is sensitive to helium concentrations as small as 2 ppm- equivalent to a leak rate of 5x 10-6 atm-cc/sec, far superior to the performance by other means of detecting leaks, such as bubble-testing. The PHD-4 sensitivity relies on Agilent’s proprietary and patented SIPD (Selective Ion Pump Detection) technology. Since it is controlled by a microprocessor, the PHD-4 is easy to use with no training required. All tuning and zeroing are handled automatically. 

1. Preventing Material Loss by Leakage Detecting and addressing leaks ensures that valuable materials are not lost due to escaping gases.
2. Avoiding Contamination Leaks can introduce contaminants into a system, affecting product quality and reliability.
3. Ensuring Product Performance and Reliability Leak-free products perform better and are more reliable, leading to satisfied customers.
4. Reducing Liability Leaks can lead to safety hazards, environmental issues, and legal liabilities.
5. Minimizing Production Output Loss System downtime caused by leaks can significantly impact production output.

• Helium’s Properties:
  • Helium, with a molecular weight of 4 atomic mass units (amu), is readily available worldwide.
  • Its low background noise makes it an excellent choice for leak detection applications.
  • Helium is non-toxic, non-flammable, inert, and not easily absorbed.
  • It allows for non-destructive testing (NDT).

• Variety of Helium Leak Detector Models: Hexo offers different models to suit your specific needs.
• Pump Options: Dry pumps or oil pumps are available for both cleanroom and non-cleanroom environments.
• Customizable Pumping Speed: Choose the pumping speed based on your process requirements.
• Flexible Types: Hexo provides options with or without carts, as well as handheld detectors.
