Met One's Model 385 provides year-round measurement of rain or snow. It features a 12-inch diameter orifice that funnels precipitation into the tipping bucket assembly.

When the tipping bucket fills, it tips and activates a reed switch. The switch closure is recorded by the datalogger, which is typically programmed to output total rainfall over a time interval such as an hour or day. If rainfall intensity data are desired, the datalogger can be programmed to record every tip or total rainfall every one to two minutes during the event.
