Aqualab Systems

The IP-enabled and highly energy-efficient datalogger OTT netDL 500 is the core of the system. Several SDI-12 sensors may be connected to the rugged logger, as it has up to 40 channels. Optionally, the measured data may be remotely transferred via the built-in Next G, GSM/GPRS modem or via satellite. The required antennas are already included in the system.

Product Highlights: Turn-key solutions for stand-alone measuring stations
Location: Gauging station, Pole mount
Power supply: Battery, Solar
Communication: Cellular, Satellite

  • Compact, turn-key, and convenient:

  • All components are pre-installed, pre-wired, and pre-configured – minimum installation operations required.

  • Standardized configuration resulting in particularly attractive value for money.
  • Rugged lockable stainless steel system cabinet – particularly designed for field applications.
  • Cabinet enclosure fitted with breathing gland for sufficient ventilation and drainage.
  • Powerful IP datalogger providing efficient power management.
  • Convenient stainless steel mast mounting bracket – for easy installation to masts of 1"… 4" (accessory).
  • Alternatively stainless steel wall bracket for safe wall mounting, e.g. in gauge station (accessory).

  • Time-saving during the installation -- station build-up and start-up can be finished within one day

  • Completely autonomous power supply -- solar power supply and Next G GSM/GPRS data transmission are offered as a standard

  • Modular design -- easy transportation to the measurement site

  • Select the most appropriate sensor for your site
