Benefits
Reliable measurements with fewer field connections
Battery power and wireless data reduce field wiring
A built-in 76Ah lithium thionyl chloride battery powers the device, with standard 4G Cat.1 communications and optional LoRa. Battery life: 5 years or more with 4G reporting once every hour. Average current is <0.22mA with a 1-hour reporting interval. No external solar panel or data cable is required. The device is secured with screws.
Stainless steel housing and ruby bearings
The device uses 304 stainless steel housing and ruby bearings. Measurement error remains within ±2% after 250,000 tipping cycles. Sealed construction supports long-term field deployment. The collector diameter is 20cm with a 45° rim angle.
Optional GPS links rainfall records to the monitoring location
Optional GPS positioning provides device coordinates to help associate rainfall records with their monitoring locations in the project platform. Select communications for the site network conditions.
