I was wondering if there is a gauge/meter or somthing that can tell me the percentage of meth to water ratio Im running. Is there something out there that reads this? Im running a 50/50 mix now but I know that meth evaporates over time so I want something to measure it to see if I need to fix my mix? Also I want to run a stronger meth mix for next year so I want to be precise with every batch I mix. Hopefully this doesnt sound stupid.
