ARG100 Tipping Bucket Raingauge (0.2mm/tip)
Services Available

Overview

The ARG100 precipitation sensor is our cost-effective solution to your measurement needs because it is manufactured in U.V.-resistant plastic by high precision vacuum-forming techniques. This allows the instrument to be robust yet still maintain all-important measurement accuracy and precision.

The ARG100 aerodynamic precipitation sensor (rain gauge), manufactured by EML in the UK. A conventionally shaped instrument interferes with the airflow around the sensor’s orifice so that the catch is reduced (as much as 25% of catch in windy conditions), and therefore precipitation measurements are significantly underestimated. The cost-effective ARG100 has been scientifically designed and developed to minimize this effect.

Detailed Description

This instrument utilises the well-established measuring principle of the “tipping bucket” mechanism. This is both the industry and scientific standard for measuring precipitation, and it provides a contact closure at each tip. This is compatible with all loggers, event recorders and data acquisition systems for a wide range of applications.

The ARG100 is capable of measuring intensities up to a limit of approximately 500mm/hr. A rainfall Intensity adjustment formula is available for the ARG100 by request or from the EML website (www.emltd.net)
