Rain Gauge Pack
This pack includes the Rain Gauge (3298) and Count/Tachometer adaptor (3296).
The Count/Tachometer adaptor counts electrical pulses (the number of times a change in a digital signal occurs). It has 11 ranges, 1 of which is calibrated to record rain fall in mm.
The Rain Gauge is a `tipping bucket' type. As rain falls the water runs down through the collecting funnel into a self-emptying spoon which tips and empties each time the equivalent of 1 mm of rain has fallen. Total rainfall is measured by counting how many times the bucket tips.
The Rain gauge is wired to a 10 m lead that terminates in a 3.5 mm jack plug which connects to the Count/Tachometer adaptor.
