Two Types to Meet Different Needs
EM300-SLD
Probe type for detecting two fixed points
with 1.5m of cable
EM300-ZLD
Rope type for detecting large areas
covered by 3m of cable
(Optional cable lengths of hundred meters available)
Leak Detection with High
Sensitivity
M300-SLD/ZLD is suitable for detecting the presence of water and remotely alerting users to potential water leak, water spillage, or floor wetness. It supports water or other conductive liquids leak detection when liquid levels reach 5mm.
3 Sensors in 1
EM300-SLD/ZLD is equipped with temperature and humidity sensors for comprehensive monitoring in one device.
- Temperature: + 0.3°C (0°C ~ 70°C), + 0.6°C (-30°C ~ 0°C)
- Humidity: + 3% (10% ~ 90%), + 5% (below 10% and above 90%)
Industrial Grade Design for Harsh Environment
