Overview

The 385 is an electrically heated rain gage that provides year-round measurement of rain or snow. It is a tipping-bucket rain gage widely used in environmental monitoring applications. The 385 funnels precipitation into a bucket mechanism that tips and actuates a switch. The momentary switch closure is counted by the pulse-counting circuitry of any of the Campbell Scientific dataloggers. The gage is heated so that frozen precipitation melts and is measured right away as a liquid.

Benefits and Features

  • 300-W heating element melts snow and ice for year-round measuring
  • High precision—tips at 0.01-in. increments

The "-L" on a product model indicates that the cable length is specified at the time of order.

Detailed Description

The 385 uses a 115-Vac blanket heater to provide year-round measurement of rain or snow. This sensor requires an adequately grounded, reliable ac power source.

The 385 measures in 0.01" increments and has a 12" diameter orifice. It funnels precipitation into a bucket mechanism that tips and activates a reed switch when filled to its calibrated level. The switch closure is recorded by the datalogger. The 385 is compatible with all Campbell Scientific dataloggers.

Before July 1994, the 385 used a cartridge heater. Met One will upgrade that cartridge heater to the blanket heater.
