  • Sold air flow gauge
Model: 100~1000mL/Min
This is a solid air flow gauge for low flow rates. The control non works perfectly from off to over 1000 ml/min. I found no problems with it.

  • Well constructed flow controller for concentrated O2 in air.
Model: 100~1000mL/Min
The listing calls out a copper connector, there is no copper obvious anywhere in the construction. The tubing connections are listed on the box as ABS. This is listed as an O2 flow meter which may be imprecise language. Appears suitable for a concentrated O2 in air flow but concerns about using an acrylic body with high concentration oxygen due to the potential fire hazard. Well constructed, nicely printed flow marks on the front that are easy to read. Did not have a method to easily check calibration but seems to be close to stated values for air flow. Nice smooth movement for the rate controller to easily adjust across the entire range at stated input pressure. Appears to have a calibration plug at the top, so can likely be calibrated if needed. Overall nice value for the price. ... show more

  • Poor flow control with needle valve
Model: 100~1000mL/Min
The flow meter is supposed to operate between 100 and 1000 mL/min. However, the needle valve only controls the flow between 200 and 300 mL/min. If you try to adjust the flow above 300 mL/min, it jumps to the maximum 1000 mL/min. The needle valve can't really control the flow and seems to be poor quality. ... show more

  • Precise & Reliable Oxygen Flowmeter
Model: 100~1000mL/Min
This CNBTR Oxygen Air Gas Flowmeter is exactly what I needed. The build quality is solid, especially with the copper connector—it feels durable and dependable, not flimsy like some cheaper models I’ve tried in the past. The control valve works smoothly, making it easy to fine-tune the flow without sudden jumps or inconsistent pressure. The readings are accurate and clear, and the 100–1000 ml/min range is perfect for my setup. Installation was straightforward, and it connected tightly without leaks. Once in use, it performed consistently, and I love how steady the oxygen flow remains even during longer sessions. Overall, this flowmeter works great and gives me peace of mind knowing I can adjust and monitor oxygen flow with precision. Definitely worth it. ... show more
