Embedded Ground Sensor

• The ground sensor, type ETOG-56, is designed for embedding in the outdoor
  surface using the ETOK-1 sensor tube.
  
• The ground sensor detects both temperature and moisture.
  
• The sensor tube, type ETOK-1, is a mounting tube for ETOG-56, supplied
  with a wood plug for covering the ETOK-1 hole during installation.
  
• Two ETOG-56 ground sensors can be connected to the ETO2-4550 Controller to
  keep large areas ice-free, even if they are exposed to a range of different
  conditions.
  
• Where an asphalt surface is used, or where easy installation is desired,
  installing ETOG-56 together with ETOK-1 is the obvious choice.
