Battery Hydrometer

I'm looking for input on a new battery hydrometer. I don't particularly care of the one I have and am looking for a good, quality, accurate hydrometer. I currently have the Superstart brand Rapid Test hydrometer and don't care for it.

Looking to see what others are using.

Then I guess I should balance things and put my two-cents in for the hydrometer that all the flooded battery manufacturers use.



I tried using a refractometer. Then bumbled around with how to extract a sample from deeper in the cell than on the surface. An eyedropper with a long stem is very fragile. One with a long hose is inconvenient to store. Returned to the Freas.

The EZ RED is a "Wonder Hydrometer" IMHO. 48 units, around 30 wildly different readings. The right choice can yield specific gravity readings to your personal choice - wotta hoot.

WHERE TO BUY

I knew Mex would come up with a picture and correct spelling. This is my reference, and yes hydrometer, not hygrometer.

But I still find I get more consistent and quicker results with a refractometer. Every so often I cross correlate with the Freas and every time results are virtually dead on.

Some were pretty close. But most were off. Some were hysterically inaccurate. I remember one testing 1.320 in 1.280 electrolyte. The vendor was a Warehouse Distributor stuck with a pallet of them. He wanted to return them EZ Red was reluctant until I had a chat with them.

I thoroughly rinse my hydrometer after each use. Don't need 100% pure water. Tap water works fine. Fill the bulb with water then slosh it. This keeps the bulb and pipette looking like new.

Some tout the hrdrovolt as the latest and greatest..

The issue with the glass unit is the seal leaks at bottom and that thing makes a mess..

I never had different readings with my ez red

I'm not sure you meant hygrometer.

frieze makes nist traceable units.

However, IMHO for most of us a refractometer is a better choice. it is much more repeatable. available on amazon.
