DIGITAL AUTOMATIC RAIN GAUGE DOHM-2013-D

Product Description Digital Automatic Rainfall Recorder, model HD2013-D The HD2013 is a reliable and sturdy bucket rain gauge, built entirely from corrosion resistant materials in order to guarantee its durability. So as to ensure accurate measurement even with low temperature climatic conditions or during and after precipitations of snow, a version with a heater which is automatically activated around + 4° C has been developed so that snow deposits and ice formations are prevented. The rain gauge is formed by a metal base on which a tipping bucket is set. The rain collector cone, fi xed to the aluminium cylinder, channels the water inside the tipping bucket: once the predefi ned level is reached, the calibrated bucked rotates under the action of its own weight, discharging the water. During the rotation phase, the usually closed reed contact opens for a fraction of a second, sending an impulse to the counter. The quantity of rainfall measured is based on the count of the number of times the bucket is emptied: the reed contacts, usually closed, open at the moment of the rotation between one bucket’ s section and the other. The number of impulses can be detected and recorded by a datalogger such as the HD2013-D DeltaOhm or by a pulse counter. The HD2013R, the version with a heater, operates using either 12Vdc or 24Vdc voltage and uses about 35W. Heating is activated around + 4° C.
