MiniPack CTD-F
|
MiniPack is a low cost, compact, robust and fully integrated CTD-F sensor suite designed to meet the demands of open ocean, estuarine and fresh water environmental monitoring, incorporating a 24 channel data logger.
MiniPack is designed to be a multi-parameter sensor data logger that can be deployed individually or as the core of a larger multi-parameter system. As such, it may be used as a discrete profiling instrument, installed on a data buoy, moored in the ocean or to form the core of a towed undulating vehicle system. It has been designed specifically for easy installation into the Chelsea Technologies Group’s range of towed vehicles.

- Description
MiniPack is a low cost, compact, robust and fully integrated CTD-F sensor suite designed to meet the demands of open ocean, estuarine and fresh water environmental monitoring, incorporating a 24 channel data logger. MiniPack is designed to be a multi-parameter sensor data logger that can be deployed individually or as the core of a larger multi-parameter system. As such, it may be used as a discrete profiling instrument, installed on a data buoy, moored in the ocean or to form the core of a towed undulating vehicle system. It has been designed specifically for easy installation into the Chelsea Technologies Group’s range of towed vehicles.
This compact instrument contains a fluorometer, conductivity, temperature and depth sensor. These sensors are coupled to a high performance data logger. For real time applications, the MiniPack is provided with a transmission system with the capability of providing power to and acquiring data from up to 16 external sensors (14 differential channels & 2 single ended channels). These may typically include dissolved oxygen, pH, PAR, up & downwelling sensors, fluorometer & transmissometers. A titanium / acetal housing contains all on-board sensors, processing boards, data transmission or internal batteries.
The highly versatile SmartMediaTM is used for pre-programming and storing of measured data. This data is easily extracted by a PC and presents data in ASCII files in engineering units, which are easily processed by propriety software packages. Data may be stored on the internal SmartMediaTM Card (for standalone mode) or transmitted in real-time up the cable using RS422 (RS232 option) format. An interface unit is available to convert RS422 (or RS232) for onward transmission to a PC. A user-friendly Windows based GUI enables error free programming of the internal logger and data extraction.MiniPack Cage 
A special cage has been designed to protect the MiniPack for deployment through the ice in Antarctic. An internal lithium battery and removable SmartMedia card means that the MiniPack has no external connectors – ideal for such a rugged environment. - Flow Through Manifold
The Flow Through Manifold is designed to convert the MiniPack from an in-situ CTD-F sensor suite to a flow through version for FerryBox and process control applications. The MiniPack Flow Through Manifold offers the following features:
- Ease of fitment / removal
- Standard flow through tube fittings
- Pressure rated to 10 Bar
- Non-corrosive materials
- Rugged Assembly
- Tail pipe connectors for ½” (12mm) bore tube
