Hydrogen Leak Detection
LOKtracer Hydrogen Leak Detector
The LOKtracer is a light weight and handheld sniffing Hydrogen Leak Detector. This low cost device has a sensitivity near 10 ppm, making leak detection in the field and in industry environments easy and accurate. The rechargeable battery can power the leak detector for up to 12 hours. With the progressive light display and indicator beeping, even a brand new user can use the LOKtracer Leak Detector without problems.
How the LOKtracer Hydrogen Leak Detector Works
The LOKtracer uses a hydrogen sensing chip that is activated in the presence of hydrogen. The hydrogen sensing chip is so sensitive, it can sense the trace amounts of hydrogen in an exhale of breath when place near the mouth. Leaks are found by flowing a 5% Hydrogen 95% Nitrogen gas mixture, Hydrogen Tracer Gas, through the piping or equipment of interest. The Sniffer head of the Hydrogen Leak Detector is placed along the piping. When a leak is present the Hydrogen Tracer Gas will escape and LOKtracer will react. When a leak is detected the Hydrogen Leak Detector will increase its beeping and amount of lights on the panel as more Hydrogen is detected. This process works even for buried or covered equipment as long as it is permeable to gas.

Frequently Asked Questions Concerning Hydrogen Leak Detection
Q. Isn’t hydrogen dangerous and explosive?
A. In 100% concentration, that is the case. We always recommend using 5% hydrogen mixed with 95% nitrogen. This mixture is green label non-combustible, thus will not ever have the ability to combust or increase the intensity of a fire.
Q. Will the hydrogen in the mixture settle out and cause an unsafe condition?
A. No, it remains mixed at all times. All inert gases remain cannot stratify. If this was the case, the air we breathe would become pockets of nitrogen, helium, oxygen and other gases that make up air. In short, if this was a true principal, we would all be dead.
Q. What size leak can the TLD.500 and the TLD.1000 find?
A. The TLD.1000 shows a quantifiable H2 leak rate and and can detect into the single digit ppm values. The TLD.500 while not displaying a quantity of H2 (has a series of lights that indicate more quantity) our testing has indicated a concentration detection into the 25-35 ppm range a leak rate of 0.25 oz/yr refrigerant gas is normal. The detection limit is actually smaller but the user cannot always distinguish that low of a signal as a leak.
Q. Which is better as a tracer gas, hydrogen or helium?
A. In the past, helium was the best tracer gas because of its availability, the equipment to detect it repeatedly and reliably and its low background in air (0.5 ppm). Hydrogen mixture as a tracer gas is now popular because instruments like the TLD.500 and TLD.1000 have improved in being able to find small leaks. Also, helium is in short supply and expensive. Hydrogen is a good choice also because of low background in air (0.05 ppm).
Q. What is the cost of the 5% hydrogen, 95% nitrogen tracer gas compared to helium?
A. 5%H2/95% N2 is about one quarter the cost of 100% helium. While there are efforts to lower the helium concentration to also lower the cost, that affects the sensitivity of the helium leak detector to find smaller leaks. Also, because the helium/nitrogen is now a mixed gas, there is a charge to mix it at the factory. So cost savings to less helium in the mixture may not significantly reduce its cost.
Q. Where have hydrogen leak detectors been used in the past?
A. Hydrogen leak detectors were used extensively in locating leaks during the telecom boom of the late 1990’s. Since then, hydrogen leak detectors have improved leading them to be used in applications where lower detection of leak rates is required. Future use of hydrogen leak detectors is predicted for detecting and locating leaks in underground water lines or pipes. Water is increasingly a strategic resource and leak detection is getting more important. Our TLD.500 starts in price at $961, allowing more plumbers and leak detection companies to be able to employ tracer gas leak detection into their portfolio of capabilities.
