BlueThumb Posted July 6, 2015 Share Posted July 6, 2015 Hi, I have an extra high precision Air/CO2 flow meter that includes a multi-turn needle valve. I use one to precisely control my bubble rate of CO2 on my calcium reactor. The brand I have is a Brooks Show-Rate and is very high-end. Connections: 1/8 NPT female thread Flow Rate: .2-2 SCFH Control: High precision, multi-turn needle valve Retail price: >$100 (low flow version is hard to find) Though your bubble rate will be too low to register flow the needle valve will easily be able to dial in precise changes in bubble rates. For Even Trade: 1000 mA LED Driver 48 VDC Power Supply Bridgelux BXRA Luxeon M Any takers? Link to comment
VW_TDI_02 Posted July 6, 2015 Share Posted July 6, 2015 What about a sale? If so, price? Link to comment
BlueThumb Posted July 6, 2015 Author Share Posted July 6, 2015 $45.00. Shipping is probably around $7. Link to comment
BlueThumb Posted July 6, 2015 Author Share Posted July 6, 2015 How about trade for some Violet LEDs? Is $45 too much? I'd go less. I'd do it for $35 shipped as all it's doing is collecting dust and I don't anticipate needing the second one as these don't really go bad. Link to comment
