TB4MM-L Rain Gage

The TB4MM tipping bucket rain gage has an 8" orifice and measures rainfall in 0.2 mm increments. It contains an internal siphon mechanism that causes rain to flow at a steady rate to the tipping bucket mechanism (regardless of intensity). The siphon allows the sensor to make accurate measurements over a range of 0" to 19.7" per hour (50 cm per hour).
