Brake Fluid Hydrometer

I wonder how accurate / precise these are?

A friend recently gave me one and it purports to measure H20 content in your car's brake fluid.
Very quick process, ~ 5 seconds once I had the master cylinder cap off.

If anywhere close to accurate with decent precision, these might be a good tool in the tech team's arsenal.

Very accurate and its in the tech box.
Only used on cars that are suspicious, not all.

I have one. Will be happy to carry it along to whatever event if someone will just remind me to do so. Otherwise, as little as I'm getting out and about these days, it'll sit on the shelf with the battery running down.
