Hydro Services RRDL3 Data Logger

The Hydrological Services RRDL3 Rain Data Acquisition System is a compact, programmable acquisition device suitable for any short or long term, remote data login application. The powerful communication interfaces and software enables the RRDL3 to alarm dial external phone numbers or to send data via radio, satellite or telephone modem. Alternatively a status report can be generated and transmitted on request.

• Tipping Bucket Raingauge Input
• Quadrature Shaft Encoder Input or Timed Analogue Reading.
• Accurate Real Time Clock
• Protection On Inputs & Outputs
• Low Power Operation
• Fully Environmentally Tested
• Programable Alarms
• RS232 Communication Mode
• Mil. Spec. Connectors (Some Models)
• LCD Digital Display ( Some Models)

Communications are two-way so that the RRDL3 can be remotely interrogated to send a status report, download all or part stored data. Alternatively, it can be programmed to automatically dial out to 3 preset phone numbers based upon reaching alarm or trend levels. It can also be programmed to send scheduled messages for river height and rainfall.

All operating parameters can be programmed remotely via a computer and modem. On line HELP instructions are available for every logger command. A full status report on all operating parameters and the battery is available on interrogation
