Upon hearing of the SilverTron being discontinued, I went looking for a suitable generator as a replacement.
The following is a summary of of what I found.
The generator that most closely resembles, and is consistant with the SilverTron design and methodolgy is the SilverBear.
You input the water volume, current limit, electrode area, desired PPM. Once started, the unit calculates the actual amount of silver added to the solution and shuts off when the set PPM is reached. I am satified that both the SilverTron and SilverBear use the same methodology to determine the endpoint of silver production.
There are differences between the two.
The SilverTron starting voltage is 28v while the SilverBear is 35v.
The SilverTron offers 0-15ma current limiting with a 1mA step between values, The SilverBear offers 100uA to 8mA current limiting.
The SilverTron has no Stirrer, the SilverBear has a built in magnetic stirrer.
The SilverBear has an optional software controller, run on a laptop that allows a wide range of programming options, the SilverTron is stand-alone only.
The SilverBear offers a what looks like a beautifully designed electrode holder and Erlenmeyer Flask, no alligator clips here!
The SilverTron allows a ppm range of 20-320ppm, the SilverBear only allows an automated maximum ppm of 30.
The SilverBear has a water test function that measures ppm, the SilverTron offers no such function.
Now that there is talk of a resurrection of the SilverTron, a choice will have to be made!
Not sure which way I will go.
Thoughts and comments welcome.
