ECRN-50 Rain Gauge (Low Resolution) FAQ's：

1、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.

2、What is the volume per tip for the ECRN-50?

ECRN-50 volume per tip: 5.0 ml/tip

Rainfall per tip: 1 mm/tip
