SRG1 Stainless Steel Pluviometer

SRG1 Rain Gauge and Pluviometer for Precision Measurement of Rainfall Amount, Accumulation and Rate

The SRG1 is a research grade pluviometer with 0.2mm tips and high accuracy during intense rainfall events. A ML1 event data logger is installed inside of the stainless steel funnel and records the exact time of each tipping event. In this manner rainfall intensity and amount are recorded. The ML1 logger has battery capacity up to 5 years and large data storage. Communication is via an RS232 cable. The SRG1 is ideally suited to remote and long term monitoring of rain events.

Rain Gauge Features

  • Stainless Steel
  • Resolution of 0.2 mm
  • Accuracy of ±2% at 500 mm/hr

ML1 Mini Log Features

  • Small and Compact
  • Low Power Consumption
  • Memory Wrap for Continuous Logging
  • Records events rather than Time Intervals

Constructed entirely of stainless steel.

  • Rain enters the gauge through an 20cm orifice, protected by distortion preventing aluminium ring.
  • Collected water passes through the debris-filtering screen and is funnelled into one of two tipping buckets inside the gauge.
  • When a given amount of water collects, the bucket tips.
    (Tip of 0.2mm is standard).
  • Tipping causes magnet to pass over proximity switch, closing it momentarily.
  • Second bucket positions under funnel for filling.
  • After rain is measured, it exits through drain tubes with screen covered holes in the base of the gauge.
  • Designed for many years of accurate, trouble free operation.
  • Stainless steel outer housing.
  • Built in level indicator and pre-drilled feet.
