The probe is pulsed with DC voltage to prevent potential electroplating. An LED indicates energization status. Choose from two adjustable sensitivity ranges based on fluid. Mounting requires an industry standard 8 pin octal socket. Choose from Single Probe or Dual Probe configurations.
On single probe models a fixed time delay prevents rapid cycling of the output relay and its load. Ten factory settings ranging from 1 to 60 seconds.
Dual probe models are available with specific pin configurations to match competitive devices.
