Review on E Z Red SP101 Battery Hydrometer by Dred Swindler

The inscription on the front informing about the testimony is falling off. This is clearly crap. I hope the company offers printed clear labels to fix them! I've had mine for about 3 years now and almost half the pressure is gone. The body can be made of polycarbonate. Strong but brittle plastic if that makes sense. IOW as long as you don't crush it or leave it in the sun it will last a long time. The only "difficulty" in using it is that the bubbles sometimes like to stick to the disc, thereby increasing its buoyancy and readability. If you get abnormally high readings. Test this cell again and tap the device until bubbles come out. I hope the company has a chemist who can recommend a suitable hydrophilic coating for the disk to prevent this sticking. It's not, but judging by the reviews, all options are absent. If your fingers aren't already flaking, I would apply a coat of something transparent on top, but nothing that would flake them. Possibly stick a piece of packing tape on the numbers. Remember that if you ever remove this tape, you'll be left with a clean device looking for a new use. Maybe a thin layer of Elmer's glue? I don't know and my numbers are too far off for experimentation. I'll have to staple some lines with a marker soon so I'll have to go through something.
