ECRN-100 Rain Gauge (High Resolution)

Research-grade rain gauge

Rain gauge for measuring precipitation and for use in scientific research. For all-in-one weather monitoring, see ATMOS 41.

Two internal tipping spoons make this rain gauge very sensitive, with one tip per 0.2 mm of rain.

Made of durable plastic that is UV, water, and frost-resistant.

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

What is the volume per tip for the ECRN-100?: ECRN-100 volume per tip: 4.02 ml/tip

Rainfall per tip: 0.2 mm/tip
