ARG 100 Rain Gauge
|
A conventionally shaped raingauge interferes with the airflow so that the catch is reduced. The low cost ARG100 aerodynamic gauge has been designed to minimise this effect by presenting a reduced side area to the wind. The gauge was designed by the Institute of Hydrology, Wallingford, UK with a profile very similar to that derived theoretically and independently by the UK Meteorological office as an ‘ideal’ shape and is manufactured and marketed under licence. The gauge is manufactured in UV resistant plastic by vacuum-forming techniques which enables production of a very rugged instrument of comparable precision to gauges fabricated in other materials, but at much lower cost.
The collected rain is measured by the well-proven tipping bucket method which provides a contact closure at each tip. This is compatible with all loggers or event recorders.

ARG-100 Tipping Bucket Rain Gauge
|
A well established and rugged rain gauge for professional use. Incorporates a tipping bucket with terminal blocks for connection to Rainloggers or any other logging device. Our standard units have a 0.2mm capacity for moderate rainfall intensity. We can also supply gauges for light (0.1mm) and heavy rainfall (0.5mm). |
