Our sender line-up has changed.

The 710-AR is our new standard sender and is ideal for most holding tanks that are in RVs today. It measures low-profile tanks that are as short as 3.5” up to 10.5” tall tanks or up to 19.5″ when two stacked senders are used. This sender has a high resolution of only 6mm for more precise measurement capabilities.

If your tanks are taller the 710-ES2 may be a better option for you. With a single sender, it can measure tanks up to 14” high or up to 26” high with two senders on the tank. It still has the same reliable measuring performance as the former 710-ES. These new senders can be combined with our old senders.
