Low-resolution rain gauge

Rain gauge for measuring irrigation events. (For all-in-one weather monitoring, see the ATMOS 41 weather station)

The ECRN-50 can be reconfigured to measure the output of irrigation systems in terms of either gallons or liters per hour.

How do I check the calibration and then recalibrate the ECRN-50 or ECRN-100 tipping bucket rain gauge?: The tipping bucket rain gauges have small stops that can be adjusted such that the bucket tips after the appropriate volume of water was collected in the bucket. Calibrate ECRN-50 when wet because a little water remains in the cup. Volume-per-tip values can be found in the rain gauge quick start guides below:

ECRN-50
ECRN-100
