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 ยฃ5 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 well

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.

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.

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.
