When it comes to keeping you safe from sneaky gas leaks, the SNDWAY SW-733B Combustible Gas Detector is like having a vigilant little guardian. It's got a nose for trouble, sniffing out methane, natural gas, and hydrogen with precision. And with its Type-C charging interface and a beefy 2000mAh lithium battery, this gadget won't quit on you—offering up to 10 hours of standby time. Talk about stamina! It delivers instant readings, sharp as a tack, with a resolution of 3PPM and a range that stretches from 0 to 9999PPM. Because when it comes to safety, 'close enough' just doesn't cut it.
