This flowmeter is a lifesaver in my line of work. i can measure the flow of gas with precision, and the connection to the regulator is seamless. According to my experience, this tool is a game-changer for any industrial and scientific setting. The sturdy build and easy-to-read display make it one of the best investments I've made in my toolkit .The only downside is the price but it's worth it for the level of accuracy it provides..
