Hydrometer

[Parker]

I'll have to do somthing soon. I tested again this morning after rinsing it in warm water for five min and it pegged it off the scale...same test five min's later and it's low again. I re-read the packaging and there is nothing mentioned about calibration.

hydrometers are tempurature sensative, so the warm water might have thrown it off.
