370-380 Series all-metal precipitation gauges measure rain and/or snow in all environments using a tipping bucket mechanism. The economical tipping bucket design allows accurate, repeatable measurements, requiring no regular maintenance. Each model in the 370-380 Series is optimized to meet particular site and sampling requirements and exceeds EPA specifications.
 

Features
  • Self-emptying, dual chambered tipping bucket
  • Jeweled bearings reduce wear and friction
  • Funnel screen system prevents debris from clogging gauge
  • Stainless steel, Teflon coated bucket
  • Corrosion resistant materials throughout
  • Bubble level & adjustable feet assure proper mounting
  • Optional heating elements for frozen conditions

 

Operation
When a precise amount of precipitation is collected in one side of the bucket, gravity tips the assembly and activates a reed switch. A momentary electrical contact closure is provided for each increment of rainfall. The sample is discharged through the base of the gauge.

The optional heating elements are thermostatically controlled to melt snow and ice and avoid evaporative loss.
