Much like Richard, 
1 Meg or 10 Meg  1 Meg in the Batch, 10 Meg in the inline. 

I would go to 1 in the inline, but the bed life is a step function. 
On the inline, 10 Meg one day goes to 1 Meg in a day or two. 
The meter in the batch cleaner only registers to 2 Meg. I'm sure it has a
similar step in the bed life.

1 meg or 12 meg. It depends on whether it is a batch type or inline type of
wash.  You would need to refer to the machine manual for an answer. It could
vary all over the place depending on the wash system, type of flux, type of
water used, and type of saponifier or solvent, if used.

Hi All!

 

Just a quick poll. When do you change your Ion exchange beds for your DI
water?

 

When the water drops to 2 megohm? 1 megohm?

 

Thanks
