A leak detector is typically quite expensive. Although this one works best with the headphones (the light proved worthless) listening for the change in pace of the beep it was quite effective in finding vacuum leaks in the glass reactors we were working with. Even small leaks, although you need to take care as the detector is very directional. So for the price it is certainly worth a shot. I am glad I gave it one.
Worked pretty well at first. But after about 4-5 light uses the head phone jack randomly stopped working. Now it’s impossible to find a leak with it. Construction quality is more like something you’d get at the dollar store. Shouldn’t be $50 (cheap for a leak detector) but more like $20.
The distance the receiver can detect a signal ("ultrasonic waves" from a leak /transmitter) is very much determined by the amplitude of the signal (ie, how loud it is, even that you can't hear it with your ears.) and to lesser extent, directional qualities and frequency. If you're just concerned with the transmitter-receiver reception, it is roughly 10-15 feet in open space: obviously, if transmitter is "buried" inside some vessel and its signal only has a very small escape hole, the effective detection distance falls to a few feet.Anyway, this detector works fine for me.
The first detector I received had the label applied upside down so that all the LEDS were covered up! So much for quality control. I pealed off the label and re-oriented it properly and was able to use it ok. The adhesive was now weak, so I returned it for a new one.The detector worked ok, though I had to learn how to best use it since the settings were somewhat quirky. Once I learned the best setting, I did find the leak I was looking for. Like any tool that senses noise, metal, humidity, etc under/in solid objects, it takes understanding of the limitations and a learning curve to use it effectively.
Was disappointed. Still wasn’t able to hear the low leak. Still chasing a leak on the semi. If it’s a loud leak you can hear with your ear ithe machine picks it up. But not a very low sounding leak. Wouldn’t suggest or buy again,
Works to find in slab leaks
Sadly it isnt as accurate as they say
I been hunting a leak for 6 months with an electronic leak detector in my a/c system. Electronic detectors couldn’t locate it. Using ultrasound detector I located the leak in 5 minutes.Great tool for the price.
Because the product not detected leakage
