Review on 💨 Uniweld NV1 NitroVue Nitrogen Indicator: A High-Performance Tool for Precise Nitrogen Monitoring by Mark Estrada

This Uniweld Nitrogen Gauge is made from machined aluminum and is easy to use. It is very compact and uses a simple flow sphere with a color bar labeled 3-5 SCFH for soldering and yellow for 20+ SCFH for flushing. It has built in 200psi over pressure protection. I made a short length of 3/8" copper tubing with a couple of flare fittings to mount in my nitro tanks for vertical use. I think this is great for a quick setup when applying nitro to solder. No more bulky and fragile nitrometers needed for soldering and all-day operations. This little flow indicator seems great for my needs.
