Have a Question? See What Others Asked

Can i use this in the sump of my aquarium rack, by just mounting the sensors in the water in the sump? ie not inline in an ro/hma system?
Tds meter should 2 digit result. should this be 3 digit? e.g 000ppm ??
I have an RO unit with a post filter to reinstate minerals, should this be installed before the post filter? Or will readings be affected?
Trying to recalibrate while disconnected from RO unit but the in and out probes give different readings, why?

Time saving inexpensive peace of hardware

Once installed which is so easy a 2 year old could do it, you just have to press the button to turn it on and look at the screen, no messing about like the hand held TDs metre. Great peace of kit at a great price.

Works great

Allows me to know what our readings coming into our RODI system and also what's coming out. Would recommend

everything but the clips

Its a very good device with nice, clear instructions in English. I have mine checking the water coming from the membrane and after the di resin chamber so I can check the performance of each component. Comes with batteries already installed but annoyingly it doesnt come with any of the little blue connector clips.

Great little product for a window cleaner

Smaller then I expected but absolutely perfect little TDs reader. Also have a handheld one and the readers are the same.Comes with battery's ready to install straight away.I am a window cleaner and will be installing this after my RO system and after my DI vessel to I can keep a clearer eye on the TDs levels.

Easy

Worked as it should

It works and is reliable.

I bought this to replace a similar device which had failed. This one outperforms the other in every way. I already have one of these which has been in use for several years alongside to one which failed and I have only just had to replace the batteries although, to be fair, it doesn't get a great deal of use. The batteries are LR44/G13/SR44W which I bought some time ago for something else but cost less than £5 for 100 from Ebay.There are no clibration adjustments so it is possibly not as accurate as some but more than adequate for most uses and with only simple on/off and in/out controls it just sits there and does the job.

Works very well, super simple setup

Very simple to setup and use, would definitely reccommend. Tip: The probes fit tightly into the T piecee - give them a good, hard push into place so yiou can see them through the top of the T.
