Note* Data transmission takes place via NB-IoT and LTE-M (CAT-M1), which requires sufficient IoT network coverage at the installation site. You can check network coverage for NB-IoT and LTE-M with any mobile network provider. Alternatively, our TechSupport is also available to assist you. The stated battery life may be significantly reduced in installations in environments with extreme temperatures (5°C to 40°C), as well as in areas with very poor cellular reception.

Note**
The battery must be replaced in a dry and clean environment. Megger Germany GmbH cannot be held liable for any damage resulting from improper battery replacement.

Typical applications:
Leak monitoring and detection on plastic pipes in water distribution networks as well as on long-distance water mains. The upgrade solution for existing EAR (Early Alarm Recording) systems.
