JIAWANSHUN Oxygen Flow Meter 0.1-1.5LPM / ⚙️ Gas Flowmeter Copper Connector for Oxygen Gas Concentrator Review

I use this with an oxygen concentrator and ozone setting. Works great for the price. Definitely able to handle high pressure.

I use it for very low hydrogen injection into the mixed atmosphere in a high temperature furnace. This enables precise control and monitoring. Very happy with it.

I was looking for a good quality children's flow regulator. It's perfect and feels solid. No problems with it so far, and I doubt there will be any problems in the future.

I purchased this product for specific volumetric measurements and it gives me confidence that the expected results are true. Its dimensions make it easy to transport and work with.

I have an O2 regulator but I can't control the actual O2 flow. I added this and am now adjusting the flow with this device which allows me to correct the predictions. I use it for brewing myself. Works perfectly.

Usage - Home brewer, wort oxygenation, beer, brewing in this review only. Oxygen Kit 2.0. All I had to do was cut the hose and connect it. Now you know who cares about notch size! I'll use later this week and update how it goes

I attached this mass air flow meter to my car smoke machine to determine flow in a closed system. The smoke machine helps to find leaks in a closed system. The mass airflow sensor used with the smoke machine helped me diagnose a leak and also when there were no leaks in the system. No flow in a closed system means no leaks. The product worked great for my use. Good build and great price.
