RG13
Tipping-bucket rain gauge, with heated RG13H variant
A field-proven tipping-bucket rain gauge for measuring liquid precipitation in weather networks and unattended sites. A precision septum ring gives an exact 400 cm² aperture, a siphon regulates flow into the bucket for stable calibration, and the RG13H variant adds automatic heating below +4 °C.
