  • Warehouses
  • Laboratories

This NB-IoT leak rope sensor can be used to monitor leaks from:

  • Heating devices
  • Air conditioning systems
  • Dishwashers
  • Washing machines
  • Pumps
  • Refrigeration units

With a 3m rope, the leak rope sensor will alert you to the presence of any conductive liquid detected along the entire length of the probe.

Using NB-IoT (Narrowband IoT), this sensor uses cellular networks to transmit recorded data. NB-IoT sensors can be integrated with any cloud platform and are easily connected by a cellular IoT SIM card. Simply insert your NB-IoT SIM card and away you go.
