Get the Industrial model by DA services on eBay. Two probes, one unit. Problem sorted.

I run 2 tds units with 2 probes each...
Tap TDS
After Membrane
After DI 1
After DI 2

I just pull out the pipe from the push fit connector anywhere on the system, fill a glass
and measure it.
-
;D ;D There is always the KISS method..
-
Well, I had an inline meter untill I broke the wires ::)
-
I have never been one to simplify that which can be over engineered ;D
-
I would never trust any inline meter - they are notoriously inaccurate. I have one on my 40-40 and it can be as much as 25ppm out.
I always use a handheld, and check it regularly with calibration fluid. If you don't do this you could be blissfully unaware that the water you think is 000ppm is actually 10, 15 or even 20 or more.
You only find out when the complaints start coming in.

Mine is just fine. Maybe if you get a cheaper model and not the commercial model. Also, you need to have the prongs in exactly the right position, like it says in the manual.

I got one of these and to be honest they are not that good.
Readings are a few ppm out from my two handhelds, but at least it gives you a rough idea as to whats going on.

and at the minute thats all i want/can afford!

Same here - I just use a handheld now - pull off a hose after the RO membranes wait a few mins until I measure it and it's down to about 12/15ppm then reconnect and do the same with the feed from the 2nd chamber of resin into the holding tank which is usually at 000 but I let creep up to 003.
Occasionally I measure what is coming out of the brush and I have never found it higher than what is in the holding tank, van tank or just before the brush. (Despite odd bits of unretrievable crud floating in the van tank!)

the cheep 1 will do the job used in conjunction wit a hand held least you get an idea if it starts to rise
