CS700-L Rain Gage with 8 in. Orifice

The CS700 funnels precipitation into a bucket mechanism that tips when filled to its calibrated level. Each tip is marked by a dual reed switch closure that is recorded by a data logger pulse count channel. After measurement, the water drains through two orifices (accepts 12 mm tubing) in the base, allowing the measured water to be collected in a separate container. 

The CS700 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 50 cm per hour. 

Benefits and Features 

• • More accurate measurement of high-intensity precipitation 
  • Extra-heavy metal construction for durability and long life 
  • High precision—tips at 0.01-in. increments 
  • Compatible with most Campbell Scientific data loggers 
  • Accuracy is ±3 percent at high precipitation rates of 500 mm/hr
