The rain [e] precipitation sensor is the latest technology that combines a self-emptying precision bucket that provides high resolution and high precision at a very small construction level.
The rain [e] is suitable to set up new measurement networks as well as connecting to an existing rainfall measurement network.
The rain [e] is lightweight and compact in design with an all metal, weatherproof housing that is highly durable to withstand the harshest environments and weather conditions.
