With this hydrometer, designed specifically for wet plate use, you can read the concentration of your silver bath directly!
If you're shooting wet plate, you need one of these. No kidding. It's indispensable for troubleshooting.
Hydrometers are used to measure the concentration of silver nitrate in your sensitizing bath. Until now, we had to make due with the specific gravity scale on a brewer's hydrometer, which meant recording the value from a newly made batch of silver and then remembering that number so we could compare it against our depleted silver bath months later. Arrgh! What a head ache.
But now, all that's changed! With this hydrometer, designed specifically for wet plate use, you can read the concentration of your silver bath directly! No more conversions, or trying to remember "what was that number I measured months ago?". Simply float this hydrometer in your silver bath and read the percent concentration DIRECTLY (I can't emphasize that enough!) from the %AgNO3 scale!
What could be simpler? Now you can accurately and effortlessly maintain the concentration of your silver bath and troubleshoot problems, making the sensitization step of the process more consistent and predictable.
Get this now. You'll thank yourself for having this on hand when trouble rears it's ugly head and things go all wonky.
The hydrometer specifics are: 0.65 inch bulb diameter, 10 inch length, %AgNO3 Scale (Silver Nitrate), 0% to 17% in 0.2% increments, Specific Gravity (SpGr) scale, 1.000 to 1.170 in 0.002 increments.
