crystal pro 3 stages DI


Recommended Posts

Hi,

I just brought a new Crystal Pro 3 stages DI. However the TDS readings for "IN" is 31PPM and "OUT" is 29PPM... shouldn't i be getting around 0 for a new set? Is 29 PPM good compared to distilled water?

Did you calibrate the TDS meter?

the resin cartriage may be loose (if it moves when you shake the canister, its loose), or it may just be that you are passing the water through too quickly. a new 3 stage DI resin filter should be able to bring the TDS level down to 0.

just of of interest, how can your 'in' TDS be 31 ppm? Singapore tap water is never that 'ion-free'

As mentioned above, I too suspect your meter to be faulty if that is the case. Incoming is already lower than SG standard....

I am collecting mine tomorrow, and was told it doesn't comes with a TDS meter :( anyone can loan me one to test?

I found out the reasons. I came to notice a small note on the equipment box "No black connection" ... and finally i discovered there are missing rubber stoppers which hold the cartriage tight in the canister. I inserted cut my filter sponge and fit into the canister to hold the cartriage tight and finally i got 0 ppm. Apparently, the LSF which sold me the DI wasn't honest enough to tell me the missing rubber stoppers. Make sure you check yours carefully when you got it.

You have to buy a TDS, or else how are you going to test.... do not assume the new unit gives you 0 PPM ... at least you see in my case. Mine came with a TSD.

bro, you should bring it back to the LFS for an exchange.

This thing itself is not cheap and you should not be shortchanged.

ming pm-ing me to let me know which LFS is that?

cheers

I agree with bro jack. You ought to at least give your supplier a call.
