Product Information

  • Monitors the continuity and insulation of underfloor heating systems. Compatible with all heaters.
  • Battery is not included and must be purchased separately. A 9V alkaline battery is required (e.g., ASIN: B00MH4QM1S). If the heating wire is cut or damaged, the continuity monitor sounds an alarm. Easy repair before the mat is covered with mortar and tile, avoiding costly future repairs. Provides constant, real-time testing of the underfloor heating system on all three connections: live, neutral, and earth. Simply connect the heating wire to the cable monitor, with a convenient on/off switch. Compatible with most radiant heating mats, cables, and floor coverings.
