Data Logger Dipper-PTEC

Benefits

High-performance: 32-bit microprocessor with 16 MB of memory for 1,120,000 readings

Low maintenance: Low operating costs, 1.5 V size C replaceable batteries, without the need to use tools (option: 3.6 V lithium batteries to maximize the service life)

Slim: Installation using 1″ tube diameter (probe)

Smart: For each measurement task – a suitable measurement routine: single value measurement, average value measurement, event control (swell mode, delta mode), flow calculation (W/Q table, polynomial), calculation and storage of salinity, TDS value and water density.

Accurate and reliable:

Conductivity measurement electrode with automatic measuring range switching, for maximum resolution (0-0.2 mS/cm; 0.2-2 mS/cm; 2-20 mS/cm; 20-200 mS/cm)
Water level: 0.05 % Measurement accuracy (= 1 cm at 20 m measuring range)

Robust: 1.4539 stainless steel housing can also be used under extreme environmental conditions (landfill sites, contaminated sites, brackish water, etc.)

Flood-proof: 2-step, permanent flood protection up to 3 m (standard), also available in IP68 (Type Dipper-APT)

User-friendly: Two clever apps are available for configuration and data read-out of the Dipper-PTEC. Operating software for beginners SEBAConfig (Windows) a comfortable user interface (Wizard) for various routine tasks. with SEBAConfigApp (Android, iOS) and the SEBA BlueCon to communicate comfortably wirelessly via Bluetooth with a smartphone or tablet with the logger.

Modular: When combined with our data transmission module SlimCom, the Dipper-PT ‘s recorded measurements are transferred remotely to your workstation.
