3. NSF C-2 Approved unit, for water use only.
3/4˝ Diameter Floats for Tiny Tanks
Our smallest LS-3 yet!
Reliable alternative to more expensive electronic sensors.
Fits smaller devices. Less material, lower cost.
Proprietary float more buoyant than competitors.
Small yes, but with BIG performance. No other 3/4˝ float switch on the
market matches our LS-3 specs. These units are ideal for potable water,
medical devices and other compact appliances, such as printers. Gems
proprietary float enables use in lighter-than-water fluids. NSF/ FDA
compliant models available at your request. Please consult factory.
