The CS700, manufactured by HS Hyquest Solutions, is a high-end tipping bucket rain gauge with an 8 in. orifice and a heavy-duty cast aluminium 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 data loggers and is used in environmental monitoring applications.Read More
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.

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
The base of the gauge is supported by three legs. A CM240 Levelling Base and Mount or a user-supplied baseplate with levelling 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.
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.

The CM240 fits the CS700-L, TB4-L, and the retired 385-L rain gages.
The following are some suggestions to try:
These rain gages don’t necessarily generate a voltage range, but rather a pulse. Depending on how the rain gage is connected to the data logger, the gage can generate a sourcing current or a sinking current pulse.
These rain gages can be connected to either.
Not registering any tips, missing tips, or double tips.
If data is not being logged correctly, there are two likely causes:
Not enough tips or too many tips.
The 260-953 Alter-type rain gage wind screen consists of 32 heavy metal leaves that hang freely and swing as the wind moves past them. The swinging leaves act as a wind damper and help minimize the effect of wind on the rain measurements without adding additional turbulence.
