SF6 Quantitative Leak Detector | Sulfur Hexafluoride Gas Tester | XHJK306
The XHJK306 SF6 Quantitative Leak Detector works on the principle that air containing different SF6 concentrations, as well as gases containing halogens, is ionized differently under the action of a high-frequency electromagnetic field. This enables qualitative and quantitative detection of sulfur hexafluoride (SF6) and halogen-containing gases such as fluorine (F), chlorine (Cl), bromine (Br), iodine (I), 1211, chloroform and Freon F11, F12, F13 and F22 quickly and accurately. The instrument is widely used to detect leaks in equipment and vessels inflated with SF6 or halogen gases across the electrical power, railway, electrical equipment manufacturing, chemical engineering and nuclear physics fire control research sectors.
Applications & Target Audience: Tailored for railway traction substation maintenance teams inspecting SF6 circuit breakers and gas-insulated equipment, chemical plants and industrial safety departments monitoring halogen gas emissions, nuclear physics and fire control research institutions, electrical equipment manufacturing workshops performing leak testing, and SF6 gas filling and recovery service companies that need high-sensitivity quantitative leak verification.
