Accidents do happen, so the cable monitor can be used to monitor a heating cable/mat during installation. Should a cable get cut, then it sounds an alarm, the installation can be stopped and cable repaired.

About this product

The cable monitor is for surveillance of under-tile heating cables and mats before, during and after installation.

The cable monitor is designed to measure the heating cable resistance and heating element insulation integrity. These are the parts of the cable that cannot be visually inspected for damage during installation.

If any major failure occurs during installation, the cable monitor sounds an alarm and the installation can be stopped immediately to allow investigation of the fault and a replacement element can be sourced or a repair can be performed without significant delay or cost.

What it will detect:

  • If ether of the heating conductors are cut
  • An electrical short between the heating conductor and the earth braid

What it will not detect:

  • Minor damage caused to the outer PVC coating or the earth braid
