The sensor should be installed, where snow and ice neeed to be melted. The sensor should follow the surface and must not be covered – it may be a few millimeters below the surface, so the melt water can run down. It should be installed in an open area away from walls etc. on a hard surface such as concrete or asphalt. The tube’s top must be completely horizontally with the surroundings.
In laying asphalt, the ETOK-1 must be embedded in the hot asphalt, then the ETOG-56 can be drawn through the tube and thus the sensor will not be damaged by the heat of the asphalt during installation. ETOG-56 measures both temperature and humidity. ETOK-1 is a conduit for ETOG-56 and are supplied with at wodden plug to cover the hole during installation. The wooden plug is placed in the tube before laying eg. asphalt on.
