Double DI with Dual reading TDS meter

Boy that was a mouthful !

So you bought an RO system with no DI, or the DI that came with your system is not up to par.

Maybe you are building your own RODI system.

Or you just use tons of water and really need to get the absolute most out of your DI.

Here is one very good answer: a twin, full size DI add on kit. Complete with bracket for wall hanging, tubing, (2) DI cartridges from Resin Tech, fittings and a Dual Reading TDS meter.

Yes a digital dual probe, dual reading TDS meter. Check the water entering your new DI system, flip the switch and check the water leaving.

Easy to operate use and maintain.

Squeeze every last good drop of water out of your DI cartridges and SAVE $$$$.

You can even replace just one DI. Swap their positions, putting the second DI in first position and the new DI in the second spot.

There are many advantages to getting every last drop out of your DI cartridge. This system comes with non- color changing DI cartridges. You can ask for color changing, but why? You have a really good digital reading TDS meter already in place, ready to save you money on non-color changing cartridges.
