260-2505 Tipping Bucket Rain Gauge

260-2505 Stainless Steel Tipping Bucket Rain Gauge

The Model 260-2505 Tipping Bucket Rain Gauge utilizes the highest quality materials and unique funnel design for accurate rainfall measurement. Rain is collected by an 8" diameter brass orifice with a precision machined edge. Collected water passes through screens that filter debris, and it then funnels into a small catchment basin. The basin is constructed so that the force of the falling water is dissipated at the basin. Water that reaches the tipping buckets has a constant head taken from a point above the bottom of the basin. With this feature, the accuracy of the gauge at the calibration rate (0.5" per hour) is extended to rainfall rates as high as 2" per hour. Buckets tip as they fill which activates a sealed reed switch. This produces pulses which can be directed to event recorders, dataloggers, or other data acquisition devices. Case exterior is stainless steel. All moving parts are chrome plated. A built-in level and predrilled feet aid proper installation of the gauge. Screens prevent insect intrusion at all openings.
