Ideal for high-intensity precipitation
Overview
The CS700, manufactured by HS Hyquest Solutions, is a high-end tipping bucket rain gage with an 8 in. orifice and a heavy-duty cast aluminum base. It measures precipitation in 0.01 in. increments. The CS700 is ideal for locations where intense rainfall events may occur. This tipping bucket is compatible with all Campbell Scientific dataloggers and is used in environmental monitoring applications.

Detailed Description
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 datalogger 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.

Additional Compatibility Information
Mounting
The base of the gage is supported by three legs. A CM240 Leveling Base and Mount or a user-supplied baseplate with leveling capability is recommended. The CM240 may be attached to a CM300-series mounting pole, or to a user-supplied 1.5 IPS (1.9-inch outer diameter, unthreaded) pipe (see Ordering Information). A concrete pad is recommended.
Wind Screen
Campbell Scientific offers the 260-953 Wind Screen to help minimize the affect of wind on the rain measurements. This wind screen consists of 32 leaves that hang freely and swing as the wind moves past them.
Data Logger Considerations
Each tip of the CS700 is marked by a dual reed switch closure that is recorded by a data logger pulse count channel.
