Pronamic Professional Raingauge


RAIN-O-MATIC PROFESSIONAL is a self-emptying and frostproof electronic rain gauge.
Consisting of an outdoor rain collector, ready for connection to a counter and a data logger or computer. The basic idea in RAIN-O-MATIC is the rain collector's measuring spoon being automatically tipped and emptied when the pre-adjusted water weight has been reached. Suitable for use in a number of applications requiring reliable and accurate rainfall measurement e.g. weather stations, schools, universities, professional gardeners, foresters, outdoor sport facilities, waterworks, purifying plants for sewage, and enviromental surveying stations.

RAIN-O-MATIC PROFESSIONAL is registering the rainfall by the water running through the collectors funnel into a self emptying spoon. The spoon is fitted with a magnet being kept in position by an anchor which implies that the spoon is emptied by a quick tip returning immediately to collecting position for collecting a new portion of water. The rain collector consists of 3 parts: funnel, box, and base plate, which can be easily assembled and disassembled without tools. The tipping spoon and it's magnet controlled suspension is designed in a way which makes no measuring inaccuracy even if the rain collector should not be exactly horizontally mounted.
