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)
