I’ve done a video comparison of three different gas sniffers. My favorite gas sniffer, aka “combustible gas detector”, is currently the TIF 8900. For this video post, I compared a TIF 8800x, a TIF8900, and a RIDGID CD-100. Just watch the video, and I think you’ll understand why I prefer the TIF 8900.
For the record, I don’t report gas leaks based on my findings with any gas sniffer; I only use a gas sniffer to quickly locate suspected leaks. I use a liquid gas leak detection solution to confirm the presence of gas leaks.
