Edwards ELD500 Helium Leak Detector With 3.0 m3/h Internal Wet Oil-Sealed Rotary Vane PumpEdwards Vacuum Part Number D13510906These Edwards ELD 500 helium leak detectors have a built-in internal wet oil-sealed rotary vane pump, pumping speed 3.0 m3/h, are fully automatic and compact, being small enough to place on the bench top. They are their most sensible design yet and offer amazing new features and control options for your facility, lab or classroom. For the ultimate control and customization for any application the ELD500 is your perfect solution for leak detection. At the push of a button the ELD500 can easily be set to work in either vacuum mode for precise measurement of leak rate or sniffer mode for identifying leak location. The minimum detectable leak rate available for this unit in vacuum mode is 5 x 10-12 mbar l/s and in sniffer mode 7 x 10-9 mbar l/s. The inlet flange on the Edwards ELD500 is DN KF25 and it comes standard with a TL7 internal calibrated leak and certificate of calibration. The Edwards ELD 500 helium leak detector operating instruction manual and product brochure can be downloaded in PDF format below. They operates on 1-phase 100-120 VAC 50/60 Hz and we offer optional accessories, such as, a trolley, transport case, remote control, spray gun, sniffer etc. They have Edwards Vacuuum part number D13510906. The Edwards ELD 500 helium leak detector offers new features such as: Contains a turbo primary pump and an internal 2.5 CFM (3 m3/hr) wet oil-sealed rotary vane backing roughing pump Quick Start up (< 2 minutes) Helium Pumping Speed 3.1 l/s Extremely fast response DN KF25 Inlet Flange Different reporting options – based on particular application needs Auto Calibration High Sensitivity Flexible application areas Maximum mobility with (optional) wireless or wired remote control ELD 500RC Modular design makes this unit very service friendly Most robust and reliable ion source (extended warranty time) Optional Accessories for The Edwards ELD500 Helium Leak Detector: Wired ELD 500 RC Remote Control PN D13550100 Mobile Trolley Cart D13550630 Helium Spray Gun PN 16555 Premium Helium Spray Probe Kit P1012177 Helium Leak Testing BasicsHelium mass spectrometry, or helium leak testing, is a highly precise means of leak detection. This technology was first developed for the Manhattan Project during World War II to locate extremely small leaks in the gas diffusion process.At the heart of helium leak testing is a complex piece of equipment called a helium mass spectrometer. Quite simply, this machine is used to analyze air samples (which are introduced into the machine via vacuum pumps) and provides a quantitative measurement of the amount of helium present in the sample. In practice, a leak, is identified by a rise in the level of helium being analyzed by the machine.Helium leak testing can identify extremely small leaks. For example, our equipment can detect a leak so small that it would emit just two cubic centimeters of helium (or the amount equal to two sugar cubes) in 320 years. While very few applications require this level of precision, this example serves to highlight the accuracy possible with this process.While helium leak detection may appear to be a simple procedure, the process involves a combination of both art and science. The user must ensure the equipment is functioning properly and the process is highly dependant upon the user’s experience. Consider this analogy: while anyone with enough money can buy an airplane, learning how to fly one takes a lot of practice. The same is true with helium leak detection-make sure your pilot knows how to fly.Why Is Helium Superior?While many gases are used in leak detection, helium’s qualities provide for superior testing. Having an AMU (Atomic Mass Unit) of only 4, helium is the lightest inert gas. Only hydrogen, with an AMU of 2, is lighter than helium. However, due the hydrogen’s explosive potential it is rarely used.Additional reasons why helium is a superior tracer gas: Only modestly present in the atmosphere (roughly 5 parts per million) Flows through cracks 2.7x faster than air Nontoxic Nondestructive Nonexplosive Inexpensive User Friendly Due to these attributes, and its high sensitivity, helium leak testing has gained broad acceptance in a wide range of leak testing applications. Helium Leak Testing’s two primary testing modes while there are a variety of testing procedures, in general there are:Two primary methods of helium leak testing: Spray Probe Sniffer Probe The choice between these two modes is based on both the size of the system being tested, as well as, the level of sensitivity required.Spray Probe: Provides Maximum SensitivityFor this technique, the leak detector is hooked directly to the system under test and the inside of the system is evacuated. Once an acceptable vacuum is achieved, helium is sprayed discreetly on the outside of the system, with particular attention being paid to any suspect locations. Any leaks in the system, including defective welds (caused by cracks, pin holes, incomplete welds, porosity, etc.), flawed or missing gaskets, leaks due to loose clamps, or any other defect will allow helium to pass and be readily detected by the machine. The source of any leaks can then be accurately pinpointed and repaired.The spray probe process is used to achieve the highest level of sensitivity. The equipment being used dictates the maximum sensitivity achievable; in Jurva Leak Testing’s case it is 2x10-10 std cc/sec. This technique does require that the system being tested is relatively leak tight prior to testing, as an ample vacuum is required for testing. However, by using special throttling devices a gross test can typically be performed. The gross test should eliminate any major leaks, permitting the use of increased sensitivity.The following are examples of systems that we test using the spray probe technique: A-bar furnaces E-beam systems Laser systems Metal deposition equipment Distillation systems Vacuum systems Sniffer ProbeFor this technique, helium is purged throughout the inside of system being tested. Due to the innate properties of helium it readily migrates throughout the system and in its attempt to escape penetrates any imperfections, including: defective welds (caused by cracks, pin holes, incomplete welds, porosity, etc.), flawed or missing gaskets, leaks due to loose clamps, or any other defect. The system’s exterior is then scanned by using a probe attached to the leak tester. Any leaks will result in an increased level of helium nearest the source and be readily detected. Leak sources can then be pinpointed, providing the opportunity for immediate repair and retest.Unlike the spray probe technique, this process is very flexible and can be adapted to meet the needs of any virtually any system in which helium can be injected. There is no practical size limitation. The sniffer probe technique is not as sensitive as the spray probe process, however, due to the amount of helium present in the air (approximately 5 ppm). The maximum sensitivity achievable under this procedure is approximately 1x10-6 std cc/sec. Nevertheless, this process is vastly superior to other traditional leak testing methods, such as: bubble testing, acoustic emission, liquid penetrant or vacuum box testing.The following list is an example of systems that Jurva Leak Testing has tested using the sniffer probe process: Storage tanks (both above ground and below) Floating roofs Underground pipelines Underground cables Aseptic systems (flash coolers, heat exchangers, fillers, etc.) Any vessel/line or system that can be pressurized

Ideal Vacuum PREMIUM Helium Spray Gun Probe Kit with 1 Liter High Pressure Cylinder, Regulator, Refill Adapter, and Quick Connect Fittings. This Ideal Vacuum premium helium spray probe kit includes a lightweight, aluminum, refillable high pressure cylinder with an adjustable, precise output regulator. The helium flow rate can be adjusted between 0 and 0.1 Standard Liters Per Minute (SLPM) on the cylinder’s detacheable regulator (1-5 psig). The reservoir cylinder is 3” diameter x 11” tall, with a volume of 1000 cc. The cylinder has a burst pressure rating of 1800 psi. We recommend it be filled normally to about 500 psig, more than enough for numerous leak detection procedures. (Do Not Exceed the Cylinder’s Rated Pressure.) In addition to being extremely portable with its refillable cylinder, this premium helium spray gun probe kit also includes a refill adapter for refilling the cylinder from a larger helium bottle, 10 ft. flexible supply hose, a gun-mounted, 1/4 turn shutoff valve, a 4" rigid stainless steel probe tip, and an 8" long flexible probe tip, all packaged in a durable, foam lined storage and carrying case. This kit is designed for use in maintenance or production leak detection applications. The supply hose has C10 quick connect fittings on either end to connect the cylinder’s regulator to the spray gun.
