thanks for your responses, Sam and Ode...

I actually built my generator based on the very same design Ode is referring to. I am temporarily using a TDS since that's what I had available, I did order the Hanna PWT for future use. One question here, can those units be used while silver generator is "plugged in" to take readings without damaging them?

I will follow your tips to improve my process. My power supply is a 30V / 500mA AC adapter by the way.

Also, what kind of reading should I be getting on PWT in distilled water to know that it's good enough? I read that TDS should be below 2, less the better obviously.

As far as the current meters you're mentioning... I'm guessing they need to get a reading of amperage and voltage... correct?

In the meantime, before I build up my generator, can I just let it run and take occasional readings with TDS/PWT to get an idea when it's time to stop??

thanks for all your help again

  Sure

Clocks can't work to predict anything unless:
1] you know where you started [a very small difference in water quality makes a huge difference in the amount of time it takes to get to a desired place.] 2] you have some idea of the current ramp up rate [aka runaway]..it's by no means linear like a clock.

 How far out depends on the generator type you're using.

If it's a constant voltage unit: The first hour you might get 1 to 10 PPM, the next, from 10 to 50 PPM..all depending where on the electrical current acceleration curve you started, as set by the initial water quality where a mere 1/2 microsiemens difference in starting conductivity between batches makes all that difference in PPM and the time it takes to get there.

A TDS meter isn't good enough to read those differences at all...not even close. Get a Hanna PWT or COM-100 conductivity meter...and/or a generator that has process control functions.

 I found reference to 2 "CS3" generators.
http://www.lwpub.com/downloads/CS_archives/CS3_plans.html

#1] A "CS3" doesn't control anything which means that you have to control IT.
 That takes instruments, knowledge and a watchful eye.
 An ammeter and a potentiometer is a good [cheap] start.

Some people get pretty good at seat of the pants/ hawk eyeball operation on generators like that.

BTW...don't forget to watch the C3. If you do forget, it can catch fire. [ A fuse on the output that's lower than the transformers max current rating wouldn't be a bad idea]



#2] A "CS3-12" from <http://www.antivirol.com/colloidal_generator.html>BIOPHYSICA does control current...but time is still a huge variable. [At least it stops ramping up and goes linear once the controlled current is reached. After 'that' point, you can use a clock but getting TO that point can vary by several hours] Monitor voltage to tell where you are. When voltage starts going down, you're at the point where a clock sorta works. Up to somewhere around 20-30 uS [microsiemens of conductivity], voltage can tell you something about PPM...like using a conductivity meter.

uS and PPM, though not the same thing, bear a [somewhat tenuous] relationship.

all right, I'm kind of confused here... I just lef it running for about 60 minutes, I take a reading using TDS meter.. and it reads 1 ppm...

thoughts?

Yes, this is normal.
