AQUAlogger® 310TY

Advanced turbidity and suspended sediment logger.

Ideal for research, water quality studies and dredge monitoring.

The AQUAlogger® 310TY is a compact instrument that measures turbidity to 10,000FTU (typical), with optional integral temperature and pressure sensors. The logger also features a tool to convert turbidity to suspended sediment concentration using in situ samples. It can be used in freshwater and ocean environments, with models for shallow and deep water. 

Key Features

  • Measure turbidity to >10,000FTU
  • Convert turbidity to suspended sediment concentration with the SSC Converter tool
  • Optional automatic wipers to minimise the impact of biofouling
  • Quick start by swiping a magnet against the logger
  • Shake the logger to check the status
  • Flexible sampling - options for continuous and burst sampling, delayed start, variable sample rates, intermittent logging and averaging

User friendly features

  • Quick start – swipe the logger with a magnet to start deploying
  • Shake to show – check the status of the logger by shaking twice. A light indicates whether the instrument is logging, waiting to start, not deployed or has a low battery.
  • Off the shelf batteries – user-changeable standard AA size batteries available across the world – purchase locally or order direct. Choose between alkaline, lithium or NiMH batteries to suit the deployment.

Deploying the logger

Four methods of setting up the instrument depending on the complexity of the deployment:
  • Basic – delayed start, burst sampling
  • Advanced – triggered logging, NMEA output, variable sample rates, sample averaging, intermittent logging
  • Re-deploy – redeploy the logger using the last regime
  • Pre-defined – load a previously saved regime file

Accessing the data

  • Log the data and access later
  • View in real time with a live view via a cabled connection
  • Upgrade to access your data wirelessly on the surface with Bluetooth-enabled Windows devices
  • Access your data subsea with Aquatec’s field-swappable comms modules:
    • Subsea display for data visualisation
    • Optical modem for short range interrogation, commanding and data download with ROVs or divers
    • Acoustic modem for transmission of real time readings
