[RE-wrenches] Fwd: Hydrometer source

[Jeff Oldham]

Search for Battery Refractometers on eBay, I got a nice one for under $25 from China, exact same item I've seen here in the U.S. for >$70. I keep a small vial of distilled water in the pouch for calibration, just a drop each time is all it takes. They often include a scale for Antifreeze readings, as does mine. I don't use my hydrometer much anymore.
