SDI-12 Rain Gauge

Precipitation Gauge

• Overview

  Whether you're new at rain measurement technology or know the systems like the back of your hand, you'll love the features of the SDI-12 Tipping Bucket Rain Gauge (H-3401)—such as the built-in microprocessor that automatically corrects errors. It also has a magnetic reed bucket tip sensor and an internal leveling mechanism with a 'bulls-eye' level to ensure high accuracy data. The Rain Gauge is available in .01 in., 0.1 mm and 0.2 mm resolution ranges.

  SDI-12 Output Data Parameters:

  1 - Accumulated rainfall since last measurement
  2 - Raw bucket count since last measurement
  3 - Total accumulation
  4 - Total daily accumulation (today)
  5 - Total daily accumulation (yesterday)
