    great product-should do well in the marketplace!

    It is a simple user friendly tool, and very useful in detecting gas leaks. This could be a big hazard as many pipes and accessories get old and wornout, and lead to leaks.

    Saves repeated recalls to work sites. Time is money you earned.

    My nephew will recieve one as graduation gift from internship and studies of plumbing.
    A recent installation of gas logs proved once again the value of quality equipment on site could have saved 5 (yes, five) return visits of the licensed plumbing business.
    My nose led me to keep calling back but I finally got a mirror, strong light and liquid soap to prove two joints leaking and was told the brickwork over the pipes would have to be removed.
    I called the owner and asked if they had the Amprobe leak detector and real pressure check device to use before any drastic costly work began.
    One of the employees had invested in the Amprobe gas leak detector. He detected the third leak at the valve, did the pressure check and the job was completed.
    Amprobe continues to reach higher in all fields for life saving, money saving direct answers .

    GSD600 5 star

    My GSD600 is a great tool, i have used a cheap tool from home depot normally but I do work at peoples homes and want the accuracy and ergonomic feel of a quality tool. We had a slight leak in a rental aprtment where I thought is was a musty smell, I took out the GSD600 and the flexable line enabled me to find a poor seal of a joint just inside the wall. All my headaches were gone and the landlord gave me a discount on my rent for repairing and diagnosing the problem for him. Very good tool, you get what you pay for.

    ✔ Yes, I recommend this product.

    It’s good but…

    I think that you have the technology for developing a specific equipment for neeeds.

    In my case, I need a 152a’s leaks detector for aerosol industry.

    I hope that you develop this device and you communicate with us.

    This thing really works

    Had new furnace installed (9-10-15) and always smelled gas every time I was around it,called the company that installed unit and after spraying blue liquid ,the tech told me to keep your window open and it is my imagination.
    Got the Amprobe GSD600 and Wow.
    Found leak at hot water heater pipe(disturbed during furnace installation?)called same company and this time after trying the blue spray I had to use the Amprobe to point the area of the leak.after a week walked by furnace room and stil smelled gas,armed with the Amprobe found leak at furnace shut-off valve,tightened nut and that was fixed.
    Gave another week to clear the area from any gas smell and again,a faint smell of gas when above hot water heater thermostat control/gas valve.
    Yesterday water heater tech was over and after telling me that I did not believe on electronic sniffers “( I have one and it is 15 years old and always gave me false alarms)”.
    He tried the green slime,than another liquid and stil could not find or smell the leak.again the Amprobe to the rescue.
    To make story short,as I am writing this,the hot water thermostat/gas valve is on order and will be delivered at home and the tech will be here the day after.
    The Amprobe GSD600 is a little pricy but the look on plumbers/tech is priceles

    Nice product for Locating Natural Gas leaks.

    Just need to wait for the Ready light and it works great. Shows digital steps for concentration. A solid dependable product.

    ✔ Yes, I recommend this product.

  11. DJBK

    Short on Necessary and Useful Instructions

    The unit is lacking a comprehensive and useful set of instructions. There is nothing about Natural Gas, which can be detected with the GSD600 because Methane is a major component. Doesn’t anyone at Amprobe know anything about Natural Gas? There is Zero information about it and no guide to the levels of gas or what they mean. Do we run out of the room when levels reach 320 or 640? How can you not include those important instructions?! Shame on Amprobe.

    The unit works, but I’m not sure what I’m reading.

    ✔ Yes, I recommend this product.

  12. Pitt2500

    Appears to do what it says

    have only used it twice & both times it found location of sewer gas leakage

    ✔ Yes, I recommend this product.

  13. Louisdeg

    Just what I needed

    I did a substantial amount of research before purchasing this meter and what it came down to was that this meter only detected 2 combustible gases methane and propane. Several other detectors I considered detected a laundry list of gasses. Since I only want to test for gas leaks and not refrigerants, paint thinner, halon etc. I chose this detector. If I could get one at this price that told me what gas it was detecting I would have gone there but those are over a thousand bucks. I used it to check an oil furnace and it detected the combustion gasses in the flue.

    ✔ Yes, I recommend this product.

    Does what it’s supposed to do

    I bought the GSD 600 to use primarily to diagnose a propane leak in my travel trailer. Although I detected the gas odorant by smell, I was not able to find the leak using a soap solution.

    The GSD 600 found it easily…it was the burner valve on the hot water heater. After replacing the valve, it was easy to check my work using the GSD 600 to make sure there was no further leak detected.

    The device is easy to use and appears to provide reliable and repeatable readings.


    ✔ Yes, I recommend this product.

    It’s a nice product

    Have not had a chance to use it – but very shortly I hope…..

    ✔ Yes, I recommend this product.

  16. Oldtechie

    Great tool

    Every time I’ve used this tool I’ve found the leak in record time. Fellow workers have used it and love it so much they’re going to purchase one too.

    ✔ Yes, I recommend this product.

  17. Hvacpeter

    Nice but may be too sensative

    Works well but I have had some fairly large leak indications that turned out NOT to be a leak. Be careful before you make a ruling.

    ✔ Yes, I recommend this product.

  18. Dutch

    Works as advertised well done .

    Thanks this product performed beautifully. If anything it might be to sensitive. It was picking up the leftover gas in the stove tubes. Great product!

    ✔ Yes, I recommend this product.

  19. Jean

    Functioned perfectly, very sensitive!

    My experience … I opened up my utility closet (which houses the clothes washer and dryer) one day and thought I smelled gas. I called the gas company and they sent someone out to check, but by the time he arrived, the smell of gas had dissipated and he couldn’t detect any leak. I was convinced there had to be a leak and I bought this gas detector so I could monitor for leaks. The closet, the main valve, and the inside of the dryer checked out okay with the main valve off, but when I turned the gas on and checked back the next day, the detector alerted me to a small amount of gas within the dryer itself. The problem – a faulty valve in the dryer. So this detector is the real deal and helped me avoid a disaster. It is worth every penny I spent on it! (P.S. I replaced the gas dryer with an electric one.)

    ✔ Yes, I recommend this product.

    Great product!!

    I am in the residential hvac field. During heating season and throughout the year this a must have. Finds and pinpoints gas leaks very well. It is sensative to pipe dope but havent found one that wasnt. Nice blow molded case and extra batteried. Is solid built and was a fair price. Only thing i would have liked to se is rechargeable batteries. Again works great

    ✔ Yes, I recommend this product.

  21. Bogwompus

    Fine product

    I was concerned it might not be sensitive enough but it’s great. I removed a black iron propane supply pipe and left it laying flat on my workbench the week before I received the GSD600. When I was checking out this new unit I put the probe at the end of that pipe and after about 15 seconds it alerted at the 40ppm level. I call that pretty darn sensitive!
    I’m obviously quite pleased with this unit

    ✔ Yes, I recommend this product.
