Intrinsically Safe Compact Data-Logger

The IS Log product is a compact, easy-to-install data logger designed to provide cost-effective solutions to a variety of environmental monitoring needs.

It offers several years of battery life and is certified for use in potentially explosive areas.

Integrating the latest generation LTE-M/NBIoT cellular modem, it also allows wireless programming and activation in the field.


Remote monitoring of sites without power supply, especially for level monitoring in the field of wastewater and prevention of flooding and overflows.

Different sensors can be used for this monitoring, including:

  • Digital Float Sensors Spill Sens
  • Ultrasonic level sensors Sonicsens 3
  • Hydrostatic level sensors

Main benefits

  • Quick installation by a single technician, without confined space entry
  • Works on the new LTE-M/NBIoT cellular networks that offer:
    — better communication in difficult locations (e.g., manholes under the road)
    — reduced energy consumption
