Just a quick question asking everyone what brand, type of hydrometer you use. I have a $14 one I bought at an automotive store but don't know if it is all that accurate. It's all glass but has no temp compensation. I have seen one called EZ Red claiming to be accurate, etc. There are many, many models to choose from on the net so I'm asking you guys to help steer me to a decent one. Or, can I calibrate the one I have to make sure it's accurate?
