Brand: Gems Sensors, Inc
When all-plastic material is desirable and tank space is not restricted. The LS-1700 Series offers broad chemical compatibility for general-purpose use.
Also ideal for oils and water. A medium-size solution for ultra-pure liquid level sensing. Made of corrosion resistant PTFE for low particle generation.
LS-1900TFE resists build-up of foreign material or sticky media. Float travel remains uninhibited in viscous or corrosive liquids. SPDT switch.
The LS-74780 Series Single-Point large size float level switch is ideal for use with aggresive fluids or ultra-pure liquids.
