https://amzn.to/3QVDPte TopTes Combustible Gas Leak Detector is sensitive to a dozen different gasses including the common ones of propane, methane and butane. Great for home appliances and camping compressed gas stoves. At almost $100 less than the Klein gas leak detector, it puts safety in the hands of almost any toolbag owner.

The Klein has more features and a much greater sensitivity. However, for many applications, having this TopTes sensor is vastly better than no sensor, and as you could see in the comparison, their performance on this common task was quite similar. If you need a more sensitive detector, by all means get one since you have specific needs. But if you are new to gas sensing and are interested in a basic affordable tool, then I can recommend the TopTes.

Note: There is a plastic film over the display that should be removed to improve clarity.
