TDS Alarm

[CEReefer]

Hi everyone, I want to install a TDS alarm, on my RO/DI System so that when TDS is above 0 on the output I get notified with an audible alarm, does anyone have a suggestion on which device to use for this purpose? I was looking at this below but the probes are 1/2”, too big for a normal RO/DI unit (which I believe is 1/4”, right?) http://hmdigital.com/product/psc-60d/

You can get 1/2 npt to 1/4 push connect adaptors

I don't know how this will effect the accuracy of the tds meter though.
