High-precision tipping bucket rain gauge for monitoring precipitation intensity and total accumulation.
The Geolook G91-600RF is a professional-grade Rainfall Gauge designed for high-reliability environmental monitoring. It is a critical sensor for geotechnical engineers, used primarily to correlate rainfall events with pore pressure changes and slope movements. The instrument utilizes a balanced tipping-bucket mechanism. As rain falls into the collection funnel, it is directed into one side of the bucket; once the calibrated volume is reached, the bucket tips, activating a magnetic reed switch and emptying the water. This process repeats, providing a digital pulse for every 0.2mm or 0.5mm of rain, allowing for precise measurement of both storm intensity and total daily precipitation.

The tipping bucket design is preferred for geotechnical monitoring because it provides a direct digital pulse for a specific volume of water. Unlike weighing gauges, it does not suffer from evaporation errors and is much easier to maintain in remote areas.
Each tip represents a discrete unit of rainfall (e.g., 0.2mm). The data logger counts these tips over time, calculating the 'Rainfall Intensity' (mm/hour)—the single most important factor in triggering slope stability alarms.
For accurate data, the G91-600RF must be installed in an open area away from trees or buildings that could block rain or cause 'shadow' effects. It features an integrated leveling bubble to ensure the bucket mechanism is perfectly horizontal.
Maintenance is simple: the funnel and internal screens should be cleared of leaves, bird droppings, or dust periodically to ensure water flows freely into the tipping mechanism.
In landslide-prone areas, a Rainfall Gauge is rarely used alone. It is usually paired with Piezometers and Inclinometers. By analyzing the data together, engineers can see how long it takes for a heavy rain event to increase pore water pressure and subsequently trigger ground movement.
This 'lag time' analysis is essential for creating effective Early Warning Systems (EWS) that protect local communities and infrastructure.
