Must have for your RO/DI

Comments: I have a hand held meter and this is spot on with the hand held meter. I love that I can get an overall idea of how my RO/DI is performing with this meter. I replaced my dual meter with this one as I was only measuring input pre filters and output after the DI. This unit allows you get a pre filter reading, post RO and post DI. Those reading allow me to better monitor when filters and membranes need changing. Yes is does not compensate for temp but its a great tool to get an idea of how your system is performing. I strongly recommend this product.
