Handheld detection instruments
Most handheld leak detectors give you a rising beep and nothing else — no sense of how close you are, no way to tell a real leak from sensor drift. Every SENSYX instrument shows leak intensity in ppm on a color screen as you sweep, so you can pinpoint a leak instead of guessing at it.
