I've had mine for almost a year now, ever since I bought my RO/DI unit. A great digital tool and makes it easy to tell when it's time to change cartridges and guarantee quality water.

Only problem is mine now needs new batteries, and they are the little round watch type batteries which are usually kinda expensive! :eek:

Does anyone local (Vancouver) know if any LFS has calibration solution, as I'm sure I'll have to re-calibrate the darn thing after the battery change?
