CS701-L

HS Rain Gauge (Plastic Base)

The CS701-L Tipping Bucket Rain Gauge designed and manufactured by Hydrological Services Pty. Ltd is ideal for measuring rainfall and precipitation in remote and unattended locations. Rain funnels into the tipping bucket mechanism and each tip is marked is marked by a dual reed switch closure that is recorded by a Campbell Scientific data logger pulse count channel. After measurement, the water drains through two inbuilt discharge outlets (accepts 12mm tubing) in the base, allowing the water to be collected in a separate container.

The rain gauge includes a siphoning mechanism that allows the rain to flow at a steady rate to the tipping bucket regardless of rainfall intensity. This reduces typical rain bucket errors and produces accurate measurements, enabling the CS701 to record intense rainfall events.
