Tipping Bucket Rain Gauge Extended, 0.2mm w/o Siphon

The Model 3525 Bucket Rain gauge w/o Siphon is the recognized standard for measuring rainfall & precipitation in remote, unattended locations. Its primary feature is a 5 inch (127 mm), high-extended funnel catch to eliminate out splash loss that occurs with machined-rim gauges during heavy rainfall. The extended catch also decreases splash loss due to moderate or high cross winds.

This new design closely resembles NOAA’s T-200B all-weather precipitation gauge’s catchment & data acquisition features.

The unit consists of a collector funnel, a stainless steel filter screen and a tipping bucket mechanism. The bucket tips when precipitation of 0.1 mm, 0.2 mm, 0.5mm, 1.0 mm or 0.01 inch has been collected. Each tip, marked by a reed switch closure, can be recorded by a datalogger/DCP & transmitted by satellite, cellular or radio.

The Tipping Bucket performs a wide range of rainfall measurements. The receiver (orifice) is 8.00” (200 mm) in diameter. The Tipping Bucket measures each 0.1 mm, 0.2 mm, 0.5mm, 1.0 mm or 0.01 inch of precipitation.

Supplied complete with a reed switch assembly, anodized and powder coated aluminum funnel, powder coated aluminum cover and base with mounting holes, Jewel Sapphire Bearings with stainless steel shafts, injection molded ABS chrome bucket, stainless steel fasteners and leaf sieve, with 10 meters of 2 conductor connecting cable.
