Dear Fabio and Kevin and others,

Maybe you remember that i was in the middle of a deforce of my wife. Well, that part is done. We sold our house, as ni one of us would stay.
So, now i moved in by my new girlfriend in Germany.
Yes, i moved countrys....pfffffff
Not easy, btw. A culture shock....hahahahahaha
Not having my lab was a bad feeling.
Today i build it almost up again.
As you can see on the pictures, is my whole collection of materials and tools in boxes.
The coming days i will put my meyer cell etc back on my new bench!
I am also looking for parts for my version of the Anderson setup.
Well, now you know why my progres was sooooo slow.

cheers

X-blade and others who want to join in:

I measured my cell in a dry state. I removed the destilled waterand dried the cell.
My 4 cells measure between 0.043nF and 0.050nF.

So what is the capacitance for these cells with destilled or tap water?
Dielectric constant of water at 20 degrees celcius is 80.1
If i multiply 0.043nF times 80.1 i get 3.4nF or 0.050 times 80.1 i get 4nF

Distilled water having a conductivity of 0.5 uS/cm (resistivity of 200 kOhms /mm)
(Tap water having a conductivity of upto 800 uS/cm (resistivity of 125 Ohms /mm)
Salt water having a conductivity of upto 56 mS/cm (resisitivity of 1.8 Ohms /mm))

If i would go for the famous 42.8khz as resonance frequency, my coils should be 3000uH in totall?
Calculation:5nF + 200kOhm resistance + 42.8khz makes a totall inductance of 3000uH.

Please shoot if my calculations are not correct.....


cheers

Hey bro is your cell the standard 4 inch rod with windows and the 2,75inch tube?

mine measures 1nf with zero ppm water and without is very low if i remember well around 10pf

are you sure your meter is ok:? ?: did you zeroed it?

the calculation is correct this form however  don't know about those numbers sources...

Dude, of course it is the standard Meyer type lengths.
My meter stands on the 2nF measurement option, which is the smallest option it has.
Then it measures 0.043 = 43pF
Something wrong here?
I still have some new / un used ones in a box. Can try to measure those if needed.

DOnt forget that the cell has been submerged for month with destilled water..
Maybe thats the reason?
Or yr measurements are not ok?  ;) ;) ;) ;)

Any body else?
