Fieldpiece SMAN2 and SMAN3
How much easier would it be using one of these tools when setting up a new system?
So I hack a new system together and don't know how much coolant to put in. Can I just hook this up and it will show me how much to make it operate efficiently? I know you can get a subcooling and superheat chart, but for the moderately challenged, this seems like it would be a useful tool. Are there better ones out there that do about the same thing? |

"With the SMAN3 you also get a built-in micron gauge".
It looks like a pretty good tool. I would not recommend something this expensive for installing a mini-split. It would be over-kill. One thing DIYers might want to look at regrading the old analog gauge set. http://i46.photobucket.com/albums/f1...r/NCL/R062.jpg This is a R410A gauge that shows you temperature of the gas (at pressure). At 217 PSI, the temperature of R410A is 74F. I'm not sure you can easily find a gauge for R290, but it should be real simple to make a T/P chart. http://i46.photobucket.com/albums/f1...ot/propane.jpg
