DH4-6000 Sensor Interface Module

The DH4-6000 is a sensor interface module that provides for the collection, storage, and merging of analog and digital data from up to eight sensors in both profile and moored modes. It can be deployed to depths of 6000 m.

 

Features

  • Complex sensor integration and data logging.
  • Simultaneous collection, storage, and merging of data from up to eight serial output sensors or seven analog output sensors in both profile and moored modes.
  • Data from any of the sensors may be viewed in real-time through its own host software while data is being collected and stored for others.
  • Supports a variety of serial-interface (RS-232) sensors as well as voltage-output (0 - 5 V) sensors.
  • Window-based software that provides DH4-6000 configuration, control, data downloading, and data processing.

Options

  • A total of 4, 6, or 8 channels, in user-specified combination of serial interface and/or voltage input (up to 7 channels of voltage input can be provided).

The WET Labs Archive Processing program (WAP) provides primary processing of data files created by DH4 data handler and ac-s and ACS-5000 meters. This primary processing consists of extracting time-stamped raw data from the archive files and applying calibration coefficients to the data for all WET Labs instruments and selected instruments from other manufacturers.

What should I use to lubricate bulkhead connectors?

WET Labs recommends keeping the connectors on your meter lubricated using a good quality silicone spray lubricant, such as 3M Silicone Spray or Loctite 8021 spray. These can be purchased at your local hardware store. Avoid silicone grease. It is messy and attracts contaminants.

Do not use WD-40. It will destroy connectors.
