WEH1201

WEH1201 is a portable helium leak detector model marketed by WEH, a German company known for leak testing and vacuum equipment. The device is designed for rapid, non-destructive leak testing of sealed components, assemblies, and vacuum systems, making it suitable for both field and laboratory use.

The WEH1201 typically operates by using a sniffing probe to introduce a test gas containing helium near the area under test. If helium escapes from the test item, the detector senses the helium and displays a leak rate, enabling the user to pinpoint and quantify leaks. The instrument generally includes adjustable sensitivity, audible or visual alarms, and data logging capabilities. It is designed to work in conjunction with WEH’s range of probes, fixtures, and calibration tools, allowing testing of small components, connectors, sealed housings, tubing, and assembled devices across multiple industries.

In terms of design, the WEH1201 emphasizes portability and rugged construction, with a compact housing and, in some configurations, battery operation for on-site use. Some setups may rely on an external vacuum pump, depending on testing requirements. The WEH product family is recognized for service support and a broad accessory ecosystem, including sniffing probes, test fixtures, and calibration equipment. The WEH1201 is commonly referenced in industry catalogs and standards as a versatile tool for quality control, preventive maintenance, and leak testing programs in electronics, automotive, medical devices, and packaging sectors.
