Amprobe GSD600 Gas Leak Detector

Reliably detect methane and propane gas and pinpoint combustible gas leakage

When working with combustible gases, safety is top priority. The Amprobe GSD600 Gas Leak Detector senses leaking methane and propane gas from closed piping systems reliably and quickly. Use it in home, industrial, and HVAC maintenance applications. The GSD600 indicates the concentration level of the combustible gas in PPMs (parts per million), which is important for safety concerns. When gas exceeds certain PPM levels, the environment is toxic and explosive. The area should not be entered until properly ventilated.

The attached flexible, stainless steel probe is 17.6-inch (447 millimeter) long and provides access to hard-to-reach areas. It also comes with both an audio and visual warning system. An audible buzzer notifies the user when gas is present and beeps more frequently as the concentration of gas increases in order to pinpoint the source of leaks. An LED display panel indicates the concentration of gas detected.

The unit automatically calibrates when it is powered on, helping to ensure measurement accuracy. A mute button silences the buzzer when using the detector in quiet workplaces, and the detector has an earphone jack for connecting a headset (not included) to the meter. The auto power-off feature turns off the unit after 10 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter’s batteries need to be replaced. It has a sensor cap that protects the sensor during transportation and storage. The unit comes with a carrying case.

Flexible probe

The GSD600 Gas Leak Detector offers a flexible probe to test hard-to-reach areas.

Audible and visual gas presence indicators

When gas is detected, the GSD600 emits a frequency tone. The frequency of the beep coincides with the concentration of the gas. LEDs also display the level of gas present in an area or room. Use the mute function in quiet work areas and utilize the LED displays, or use earphones for hearing the meter in loud environments.

Earphone Jack

The GSD600 features a built-in earphone jack with mute function (earphone not included).

    Buyer BewareThis gas detector worked once and that one time was very problematic. There were no problems with the shipment (as always MyMotorhomeLife and sellers provide the highest quality services) as it was delivered in brand new condition (I turned it on at that time, however, I had no gas samples to test it with, so it went into storage until time for real world application). Some time later, while on the job, I needed to use this for a possible gas leak detection; turned it on; waited for the calibration; etc. and it gave only sporadic measurements (LED lights and audible signal), then died. I put new batteries into the detector, but it then would not even activate. So, apparently I received a bad device, so be it. I contacted the manufacturer who informed me that it is not a repairable item and that I could “feel free to purchase another one”. That’s the only option offered: purchase another detector. Also, another reviewer states that the detector quality is very low/cheap; I agree with that reviewer – it is not field grade quality and seems as if it would not last very long even if this detector had worked to begin with. It is nowhere near worth $168. I paid $168 (at the time of purchase, not counting tax and shipping), so $168 wasted. This may be a rare incident, however to any potential purchasers, beware as you will have zero guarantee of this detector working and if it doesn’t, the manufacturer will offer zero repair/refund/replacement.

    DisappointmentAfter 2 days messing with a gas line and using this detector I have to say it’s a disappointment. I have old existing gas lines and couldn’t find the source of a 10 lb. air pressure test leak. I refilled the line with gas, and used the gsd600. It was accurate at finding a leak at my meter, but missed other leaks or gave me false readings. How do I know? The gas company came by to fix the meter issue and let me use their $3000 leak detector, so I was able to substantiate the missed and false readings the gsd600 gave me. These missed and false readings were driving me crazy in trying to diagnose the problem. Its not that it can’t work–it does, but only in certain situations, which can be maddening when assuming it works all the time.The gas company person also showed me how the soap and water method can detect even the smallest leaks (provided you have access), which can confirm what the meter says.In my instance, the leak was at old joints (not at the appliance valves, as you might expect). My discovery was that the air pressure test (10-15 lbs) is significantly higher in poundage so that old joints show a significant leak using this test, but not when using the much lower pressure of normal natural gas. It took the expensive meter to find them.I hope others can benefit from my few days of plumbing purgatory. BTW, methane is one of the main components of natural gas (see gas co. website), so this detector should be suitable. Why Amprobe doesn’t say natural gas is a mystery.

    Good for Pinpointing Leaks, not for Deciding if there are Any LeaksThis tool has been handy for me when I want to pinpoint leaks. It is mostly useless for just waving around in a room to determine if there is a propane leak somewhere. I smell the propane odorant LONG before this device picks up anything. Another thing that I find strange about this device is that if I hold it two inches away from a leak, it won’t detect anything even if I can smell it from 2 feet away, but if I then move it closer, it will detect it at a high level – but then if I move it back away from the leak, it will continue to detect the gas. It might be a time delay, but I think it might be an electronic noise filter, meant to prevent false positives.Oh, and one extremely annoying feature of this is that it turns off automatically when “not in use” for ten minutes. No big deal, right? Except that it takes a full minute to calibrate itself when you turn it back on. You can’t just hit a button every few minutes to keep it on, either – the only button on the thing is the on/off button.

    Very happy with this unitI worked a ten year stretch as an inner city utility lineman, and we had explosimeters that cost a couple of thousand dollars apiece to check for gas in manholes. Needless to say, I was very skeptical of a gas sniffer for a little more than 150 dollars, but I bought one anyway, and I immediately found a leak in my home that has been elusive for 20 years. After multiple bubble tests from a half dozen plumbers who didn’t find anything and due to the fact that only an occasional whiff was discernable, I assumed the source of the odor was just a little unburned gas runoff of a late closing valve after a duty cycle from my boiler or water heater. When the smell became more constant, I knew I had to do something. After getting this unit, I moved the probe near every joint in my home system and found nothing until I got close to a very old valve, a quarter turn valve, but not a modern ball valve. Soap solution couldn’t detect its leak point because there was an extruded shroud around the recessed swivel point of the valve shaft, which turned out to be the culprit, and it couldn’t be reached with a soap brush. Very happy with this unit.
