Edwards ELD500 Helium Leak Detector

Edwards ELD500 Helium Leak Detector

Edwards ELD500 is a helium gas leak detection device designed to provide high accuracy and ease of use. This tool is very useful in various industrial applications, including vacuum system testing, manufacturing, and research. With the ability to detect leaks at very low levels, the ELD500 is a top choice for engineers and technicians.

Key Features

• Sensitive Detection: Capable of detecting helium leaks at very low levels, ideal for critical applications.
• Intuitive User Interface: Known for its easy-to-read display and simple controls.
• Portability: Compact design allows for use in various locations.
• Speed and Efficiency: Accelerates the testing process compared to traditional methods.

How to Use the Edwards ELD500

1. Prepare the Device:

   • Ensure the ELD500 is connected to a power source and turn on the device.
   • Allow the device to warm up according to the manufacturer's instructions.

2. Prepare the Test Object:

   • Ensure that the object to be tested is clean and free from contaminants.
   • Seal off areas that do not need to be tested for more accurate results.

3. Create a Helium Environment:

   • Connect a helium source to the device and set the pressure as needed.
   • If using a vacuum chamber, create a vacuum in that chamber.

4. Inject Helium:

   • Direct the helium nozzle or probe to the area to be tested.
   • Slowly release helium around the test object.

5. Leak Detection:

   • Move the ELD500 probe around the object to detect leaks.
   • Monitor the device display for any indications of helium leakage.

Methods Used for Leak Testing

1. Helium Injection Method:

   • Description: Helium is injected into the tested system or chamber. The device then scans the area for leaking helium.
   • Advantages: Highly sensitive and can detect small leaks.

2. Pressure Drop Method:

   • Description: The system is tested by measuring the pressure drop in a closed chamber. If the pressure drops faster than expected, it indicates a leak.
   • Advantages: Useful for larger systems where helium injection is impractical.

3. Vacuum Test Method:

   • Description: The chamber is tested under vacuum, and then helium is introduced to the outside environment. Leaks will allow helium to enter the vacuum chamber.
   • Advantages: Effective for detecting leaks in vacuum systems.

How to Know When There is a Leak

• Visual Indications: The ELD500 display will show an increased value if helium is detected. Typically, the device has color indicators or graphs showing leak levels.

• Audible Alarm: Many models, including the ELD500, come equipped with an audible alarm that sounds when a leak is detected. This provides immediate feedback to the user to take action.

• Increased Readings: If you see a rising helium concentration reading during scanning, this indicates a leak. Stable readings suggest no leaks.

• Data Logging: Some devices allow for data logging that can be analyzed to identify leak patterns. This is useful for long-term monitoring.

Comparison with Other Products

1. Inficon HLD5000

• Sensitivity Detection: Very sensitive but more expensive.
• Additional Features: Advanced data analysis and better connectivity.
• Drawback: Larger size, less portable.

2. Leybold L300

• Sensitivity Detection: Similar to ELD500.
• Advantages: Operates in a wider temperature range.
• Drawback: Higher price and less intuitive user interface.

3. Agilent 9810

• Sensitivity Detection: High, but slower response time.
• Features: Options for testing various types of gases.
• Drawback: More complicated to operate.
