TDS "EZ" Meter
Just replace a Culligan RO system with an ISO Pure system. Felt I needed a way to monitor the water quality, as our LV water is terrible...450+ TDS from the tap. The TDS monitor is easy to use and very reasonably priced. Culligan used to test every other month with a larger industrial-looking unit...with the RO functioning, they were reading 30-35ppm TDS. With my ISOPure RO system, my reading has been 19 on two tests, two weeks apart...the tap reads about 456ppm! Thus far, I am very pleased with my purchases from ISOPure. Phil M.
