4SEEKER Helium Leak Detector

The Redline Chambers 4SEEKER is a mass spectrometry helium/hydrogen leak detector completely auto-tuned with an internal calibrated leak standard, a monochrome display that shows the leak rate in either linear or logarithmic bar graphic. It has an audible alarm, sniffing and hard vacuum detection methods, and three testing modes: gross, fine, and ultra-fine that can be disabled/enabled under the convenience of the test. The 4SEEKER comes with either a rotary vane backing pump or a diaphragm backing pump.
