CS700H-L Heated Rain Gage

Rugged, accurate, ideal for high-intensity precipitation, even in freezing conditions

The CS700H, manufactured by HS Hyquest Solutions, is a high-end heated tipping bucket rain gage with an 8 in. orifice and a heavy duty cast aluminum base. It measures precipitation in 0.01 in. increments at temperatures down to -20°C. This heated rain gage is ideal for locations where intense rainfall events may occur, and it is used in environmental monitoring applications. 


The CS700H 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 CS700H contains an internal siphon mechanism that causes precipitation 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. 

The CS700H includes an internal snow sensor that is activated when the air temperature drops below 4°C. If the snow sensor detects snow in the catch area (funnel), the heating elements automatically turn on and keep the funnel temperature at +10°C. To conserve power, the heater goes into a wait mode when snow has not been detected for 18 minutes. The heating element is also automatically deactivated when the air temperature drops below -20°C.
