Valeport fastCTD - Fast Profiler

Add in an integral fluorometer based on Valeport’s new Hyperion range, an optional Bluetooth communications module and the miniCTD Fast Profiler offers a unique and versatile solution.

Sensors

Conductivity

• Range: 0 – 80 mS/cm
• Resolution: 0.001mS/cm
• Accuracy: ±0.01mS/cm
• Response: 30 milliseconds

Pressure

• Range: 50, 100, 200, 300 or 600 Bar
• Resolution: 0.001% full scale
• Accuracy: ±0.01% full scale
• Response: 1 millisecond

Electrical

• Internal: 1x D cell - 1.5V Alkaline or 3.6V Lithium
• External: if fitted with a connector 9 – 28V DC isolated
• Power: <250mW
• Connector: SubConn MCBH10F (if fitted)

Sampling Modes

• Continuous: Regular and synchronous data collection from all sensors up to 32Hz
• Profile: Data is logged as the instrument descends (or rises), by a user defined pressure difference, through the water column.
• Rapid:
• Once the instrument is set to run mode no data is logged until a programmed trigger depth is reached (for example, 2 metres below the surface).
• Completely programmable, the device can be set to record down cast data only, for example, when the probe stops descending and rises by a defined amount logging is stopped.

Communications

• The instrument is designed to operate autonomously, with setup and data extraction performed over a Bluetooth connection with a PC before and after deployment.
• Multiple profiles can be recorded in the instrument by switching it on then off with the magnetic switch key. Bluetooth auto-pairing and discovery make connecting to the instrument simple and robust.
• The instrument can also operate in real time or cabled comms. Supplied with a traditional SubConn connector with a choice of communication protocols fitted as standard and selected by pin choice on the output connector:
