Helium Leak Detectors

Intuitive and easy to use built-in digital display, with additional RS-232 and RS-485

A 95% nitrogen 5% hydrogen mix can be used as well. Your Reliable Partner from Applications Support to Service

Pressure decay also does not allow you to pinpoint the specific location of the leak using a tracer gas. The Helium Leak Detector measures the helium concentration inside your system, allowing you to pinpoint the location of the leak quickly and easily, saving you time and money.

Electronics

Our range of leak detection solutions ensure the safety, security, and consistent performance of research, vacuum, and industrial process systems. There are two aspects of leak technology worth examining: leak detection and leak measurement. Our Helium Leak Detector (HLD), PHD-4 sniffer and C15 component leak detector are rugged, precise, and easy-to-use instruments that accurately and efficiently detect leaks in an array of industrial applications.

Dedicated Instruments Proven in the Field

Features

This also includes the evaluation of new leak testing products at the customer’s site. Compact design allows for flexibility and versatility in use for most environments. Tightness (or “the absence of leaks”) is required for numerous reasons, including: to ensure and maintain the pressure/vacuum; for product safety; for environmental standards; and for process efficiency. You’ll want to protect your investment so you can be assured that you are maximizing your throughput, producing reliable results with the greatest accuracy and sensitivity, and ensuring your equipment is fully compliant with industry regulations.

That’s the easy part.

Our knowledgeable staff is here to help you rent the right equipment to fit your needs. Research & Development. In addition to surface helium, “standby” helium is also contained in O-rings which act like sponges, whilst also providing a good indication of how clean the unit is.

It doesn’t matter whether you are looking for water, oil, fuel, refrigerant, gas, steam, air or vacuum leaks.

Applications

Based on the ionization current the leak rate is then calculated. Fast helium pumping speed allows for quick, accurate measurements. Vacuum Components. Automotive. UHV Tech Services Inc’s rental helium leak detectors are a proven method to provide an extremely high success rate pinpointing leaks.

Modern helium leak detectors are able to constantly measure and calculate this internal (background) level and automatically subtract this from the leak rate measurement.

They are equally well suited to both service testing and series production. Of course, this is an extreme case, but as vacuum pressures get lower and lower, even the most seemingly secure and pristine of systems will soon show themselves to be less than tight. Helium mass spectrometers are a cost efficient and safe method of non-destructive leak testing.

The removal of this surface helium is called “degassing” and starts when all of the gas has been pumped out, once the molecules have been “desorbing” from the inside surface of the metal.

Understanding leak testing is essential…

Such degassing by lowering the pressure or by heating the chamber surface is not unusual, but even then does not totally eliminate all the gas at the surfaces. This reference reading provides the “background noise” for helium, which can be thought of as the ambient level of helium. No leak is too small or too big to escape our leak detectors. It is true that everything leaks, but what we most often need to know is what kind of leak, where leaks are, or what is the actual total. But how do you choose the right leak testing solution and ensure you’re getting the most out of it? That’s where we come in. For clean research applications, HLD configurations employ clean, dry, quiet scroll vacuum pumps. The majority of this background helium is contained in between 100 and 150 micro-layers of gas molecules and is permanent gas (contained in the air) that is in the leak detector, pumps, test part etc.

Our detectors will locate and measure the size of leaks into or out of your system or containing device – no matter how small the leak is. With a High Vac Depot leak detector, the time and money required for maintenance and troubleshooting of your products will be reduced to a minimum and your ongoing operating costs will be significantly less. With a High Vac Depot leak detector, long training periods or errors in handling are simply a thing of the past.

The reference (or background) reading for helium is an important part of the process. In most helium leak testing applications, one uses a mass spectrometer (leak detector) tuned to detect helium.

Analytical Research and Instrumentation

Our leak detectors feature automated start-up and calibration for maximum productivity, built in application set-ups, and an array of accessories to make any leak detection process simple.

High Vac Depot leak detectors not only are at the forefront of technology and offer the highest performance, but are also very easy to operate. The gas from any potential leaks is collected and pumped into the mass spectrometer for analyzing, and any value above the background trace of helium is evidence of a leak. Being inert it is relatively safe to use and will not react with any of the materials within the part to be tested.

leak rate of a part or system. A High Vac Depot leak detector, for example, is so highly sensitive that a release of less than one millionth of a gram of gas can be shown to be a leak. Products and services are continuously optimized in close cooperation with our experts. Helium leak testing is generally more sensitive than using pressure decay techniques.

From miniature electronic units right up to large-volume vessels, from media escaping from vacuum systems to gases entering them – the uses for leak detectors are as broad as the range of industrial products. The spectrometer itself works in the following way: any helium molecules sucked into the spectrometer will be ionized, and these helium ions will then “fly” into the ion trap where the ion current is analyzed and recorded. Helium detection works in the following way: the unit being checked is either pressurized from within or else pressured from without with helium.

Leak detectors: the answer to all your leaks, no matter how big or small

The extensive range of our Vacuum leak detectors provides the answer for all these requirements. After installation of your new leak detector, we support you with world-class service and troubleshooting expertise, if needed, to get the most out of your leak detector. Exceptional reliability from proven measurement systems. Helium is one of the smallest gas molecules and is inert.

This desorption starts at a pressure of about 10-1 mbar.

Pinpoint leaks in pipelines, cables, underground tanks, pressurized systems, or vacuum systems by detecting the smallest trace amount of helium that may be escaping.

Our Vacuum leak detectors trace every leak.

High performance system

Ion source utilizes two long-life iridium filaments, yttrium-oxide coated with 3-year warranty. When your system has a leak, the concentration of helium in that area will be higher than in other areas of your system. The leak detectors we sell are multipurpose helium leak detectors for detection of lowest detectable local and integral leak rates.
