The ARG314 (manufactured by EML) is Campbell Scientific's recommended solution for many hydrological or meteorological applications such as weather stations and flood warning systems.
The ARG314 is a versatile gauge suitable for climates with all types and intensities of rainfall. The injection moulded UV-stabilised material from which the gauge is made means that the ARG314 is an extremely robust and versatile instrument, ideal for applications where data precision and accuracy are critically important.Read More
The internal tipping bucket mechanism has been designed to ensure maximum performance repeatability.
The ARG314 is a UV-stabilized injection-molded plastic replica of the very successful, highly accurate aluminium SBS range.
Traditional cylinder-shaped rain gauges are inaccurate due to the effect of wind blowing over the orifice. The physical presence of the gauge causes air to accelerate, carrying rainfall away from the collecting vessel. The effect of this can be up to a 20% reduction in rainfall catch. The unique aerodynamic shape of this range of scientific standard rain gauges reduces this effect, ensuring a high level of confidence in the accuracy of our measurements.
Cables are available in 6 m, 10 m, 15 m, 20 m, and 30 m lengths.
