    • Easy-to-use Software includes setup program.
    • Terminal strip with screw terminals for I/O and power connections
    • Operates 8-16VDC
    • TCXO real-time clock with battery backup (+/-4ppm)
    • Built-in solar panel regulator
    • Support for up to 16 measurements of the following inputs:
      • •      SDI-12/RS485 (shared as is done in the Bubbler)
      • •      5 Analog inputs:
        •           1. Two (2) single ended inputs (range 0-5V)
        •           2. Two (2) differential inputs (range +/-39mv, +/-312mV, +/-2.5V) 3. One (1) 4-20mA input
      • •      2 digital inputs. They can be used for tipping bucket, frequency, and on/off inputs
      • •      internal temperature
      • •      Battery voltage
    • Options to average or accumulate any measurement.
    • Lightning protection (Gas Tube) on all external inputs.
    • User specified equation on any measurement .
    • User specified alarm detection on any measurement.
    • 2 LED for verification/diagnostics.
    • Log capacity of 240K of data accessible via GPRS and direct connect
    • Switched Battery Output
    • Also operates as a standalone recorder without Telemetry
    • USB slave for serial connection to PC. THE USB PORT WILL NOT SUPPORT typical USB devices like memory sticks, modems, etc.
    • RealTime Clock operates with internal lifetime battery
    • Telemetry via GPRS
      • 1. Periodic transmissions at user set times with data in user selectable format (pseudobinary B, C, SHEF & ASCII)
      • 2. Support for primary and secondary master stations via GPRS
      • 3. Alarm transmissions as they are detected.
      • 4. Diagnostics to help track of the amount of data being sent and the performance of the telemetry
      • 5. Support for remote commands for data collection, maintenance or control of two on/off devices
      • 6. Optional authentication of incoming messages to insure they are from a trusted source & optional authentication of messages sent to SUTRONWIN via GPRS
      • 7. SMS transmissions if GPRS fails or in place of GPRS
      • 8. Extremely affordable
      • 9. GPRS modems use wireless cellular technology and provide data access in most areas where a typical cell phone works.
    • Surface waterlevel,flow and quality
    • Groundwaterlevel and quality
    • Offshore X‐Linking
    • Mining / geotechnical
    • Weather X‐Linking and warning
    • Oceanic X‐Linking and warning
    • Oil and gas production
    • Any low‐power,remote data acquisition system
