simultaneously measured, and surface conditions (dry, wet, or icy) are determined by a logic circuit.  The monitoring probe is a two electrode probe which is customized for the desired application (see Figures 1 and 2). </div> <div> The probe is a part of the monitored surface.  It is glued or bolted to the surface and connected with a short cable to the electronic monitor (see Figure 3). </div> <div> The normal signal output is a standard voltage (0 to 5 V) or current (4 to 20 mA) output which can be connected to a recorder (see Figure 4) and a three relay output for alarms and signal lights.  Digital output is provided on request. </div> <DIV ALIGN="LEFT"></DIV> <div>      <IMG SRC="113f48a0.jpg" border=0 width="500" height="138" ALT="Probe for runways and roads" ALIGN="BOTTOM"
