SpectraPure's NEW Ultra-Precise Auto Top-Off System now offers 10 pump speed settings and 10 duty cycle settings making it the most adjustable ATO on the market. Easily programmed to deliver as little as 6 ml/min (0.1 gph), or as much as 190 ml/min (3 gph), the new Ultra-Precise ATO may be used in either fill or drain mode, and is capable of delivering water up to 60 feet above source or drawing water from 25 feet below! That's because, like it's predecessor UPLC-II, the new Ultra-Precise ATO incorporates our ultra-dependable, kalkwasser and run-dry safe LiterMeter Gen-6 Peristaltic Pump. Thanks to the super-grip force of our newly developed Magnetic Probe Holders, liquid level sensor & limit tubes are held firmly in place...right where you set them...and will work in tanks with wall thickness up to 3/4 inch! Switching power supply included.
