The TR-4 is a compact, rugged tipping bucket rain gauge with a 4" (100 mm) collector, designed for networks that need reliable rainfall data without the cost of a research-grade sensor.
How It Works:
Rain enters the knife-edge collector and is funneled into a precision tipping bucket. When the bucket fills, it tips, triggering a momentary switch closure that records each increment of rainfall. The bucket empties automatically with every tip, and water drains out of the gauge, so there’s nothing to empty or maintain between readings.
