EM300-ZLD Zone Leak Detection Sensor

Zone Leak Detection Sensor

EM300-ZLD is a compact zone leakage detection sensor for detecting large areas of the presence of water (or other liquids) and transmitting alarms using LoRaWAN® technology. With this low power consumption technology, EM300-ZLD can work up to 5 years with a 4000 mAh battery.

EM300-ZLD Zone Leak Detection Sensor also integrates temperature and humidity sensors, which have a great use for applications such as pipe leakage monitoring, basement flooding, pump failure, etc.

Prevent Water Damage

Through instant water leak detection, the spot/zone water leak detector will help prevent potential water damage to properties or assets.
