Forensics Detectors offers sensitive Nitrogen (Oxygen) Analyzers to detect elevated levels of nitrogen gas. Nitrogen detection is important for nitrogen storage, nitrogen purge systems, nitrogen leaks, and nitrogen personal protection due to oxygen depletion.
A Nitrogen Gas Detector is used to detect a leak in Nitrogen via measuring oxygen concentration. When storing nitrogen, using nitrogen, or trying to find a nitrogen leak, it is best to use an Oxygen Analyzer to find a reduced oxygen purity. The FORENSICS nitrogen analyzer (which is actually an oxygen analyzer) is an excellent option for those that would like to find any displaced oxygen due to nitrogen. This nitrogen detector is perfect for checking leaks in nitrogen purge systems, nitrogen containment, nitrogen in a pressurized flush situation, pipe purging, N2 leak analysis, and other applications. The oxygen gas analyzer measures oxygen content in the weld chamber down to 0.01% (100 ppm). Based on our industrial analyzer platform, the built-in pump is easy to use, light, and very portable.
The nitrogen gas analyzer measures the oxygen content down to 0.01% (100 ppm). Based on our industrial analyzer platform, the built-in pump is easy to use, light, and very portable. Simply insert the probe to the tubing with filter and onto the analyzer barb. The user has full pump control, withdrawing small or large quantities of air with the built-in pump.
A nitrogen gas leak analyzer is perfect to check lines, joints, connectors, valves, spigots, or part of a liquid or gas nitrogen distribution system for nitrogen leaks. These detectors require pump air, to achieve point sampling at a certain specific location.
