Does anyone have a DI meter built into their RO/DI?

An inline TDS meter is invaluable. Dual is nice for measuring both source and post-filtered water
Inline gives you the option of monitoring your filter media and checking output before you fill your storage container

Hanna makes a great dual inline that sells for $30 from BRS and $36 from J&L

Buy a bottle of cal solution and check it once a year, or when you suspect it could be off
