ECO-PAR™

Provides highly accurate measurements of PAR (400–700 nm) in all aquatic environments.

The ECO-PAR™ sensor provides highly accurate measurements of PAR* (400–700 nm) in all aquatic environments.

Equipped with quality precision optics and proven Bio-wiper™ technology, the ECO-PAR™ sensor can be deployed for extended periods without a reduction in data quality caused by biofouling. Additionally, the ECO-PAR™ has optional internal data logging and power capabilities, precluding the need for an external logging device and battery pack.

What is the back scattering angle of my ECO instrument?

WET Labs ECO Centroid Angles for Back Scatter Measurements

The WET Labs’ ECO sensors have multiple back scattering angles depending upon type of sensor. This document will describe these angles based upon the type of ECO sensor selected by the customer.

Single Channel Sensors:
Single channel ECO back scatter sensors have an in-water centroid angle of 124°.  These include the following ECO models: bb, NTU.

Dual Channel Sensors:
Dual channel ECO back scatter sensors (back scatter at 700nm paired with chlorophyll fluorescence) have an in-water centroid angle of 142°. These include the following ECO models: FLNTU and FLBB versions along with OEM variants of these sensors (AP2, 2K, SLC, RTD, SB variants).

Three Channel Sensors:
Three channel ECO back scatter sensors (individually paired LED source with detector) have an in-water centroid angle of 124°. These include the following ECO models: bb3, BBFL2, BB2FL and Triplet-w family.

Combined Three Channel Sensors:
WET Labs’ combined three channel ECO back scatter sensors (back scatter at 700nm paired with chlorophyll fluorescence along with either another back scatter or FDOM channel) have an in-water centroid angle of 124°.

These include the following ECO models:
FLBB-CD, FLBB-BB along with OEM variants of these sensors (2K, AP2, SLC, REM, BOSS, 6K). MCOMS and SeaOWL UV-A: WET Labs’ MCOMS and SeaOWL UV-A back scatter sensors (back scatter at 700nm paired with chlorophyll fluorescence along with either another back scatter or FDOM channel) have an in-water centroid angle of 150°.

What is the input voltage range for my instrument?

What are SIP files?

Files that are delivered with Sea-Bird Scientific and third party equipment to describe the sensors data output and calibration coefficients come in two types. Calibration files or *.cal files and telemetry definition format files or *.tdf files. In some cases, systems are created that network many sensors together and their combined data is provided in one serial output. The simplest example is a HOCR sensor that generates both light and dark frames. A more complex example is a HPROII profiling system that may contain as many as 5 sensors and 7 individual calibration and tdf files. These files must be used to both collect and process the data. This can become quite confusing to keep track of all these files so Sea-Bird Scientific developed SIP files. All CAL and TDF files required for a system are zipped using winzip and the extension changed from *.ZIP to *.SIP. The file name includes the system description (usually the network master serial number) and the creation date. This SIP file can then be used in place of individual files to collect and process data.

How do I protect my ECO from bio-fouling?

ECO instruments are designed for long term deployment capabilities with low power requirements, a large memory and an available Bio-wiper™. The Bio-wiper™ on the ECO was designed to protect the optical surface and has been very effective under most conditions.

If extra protection is required to prevent marine organisms from attaching to the instrument body near the optical head and interfering with the operation of the Bio-wiper™ we suggest using copper foil tape. The GoMOOS project developed a technique for their ECO sensors and WET Labs recommends this technique:

Apply electrical tape under the area where copper tape will be applied. This protects the meter from the significant adhesive residue of the copper foil tape.

Apply the copper tape to the prepped surfaces. There are different width copper foil tape options, with non-conductive adhesive, available from McMaster-Carr. NOTE: when applying the coper tape, the adhesive should not be touched. This will cause the tape to not stick to the electrical tape on the meter. When submerged in salt water, the copper will adhere more closely to the meter.

As long as the electrical tape is used, this technique does not violate the ECO warranty and WET Labs will service instruments that have had copper tape applied to them.

Important! Do NOT apply copper tape directly to the meter. Its adhesive is extremely difficult to remove. Meters returned to WET Labs wrapped in copper tape without the electrical tape preparation will have additional service charges applied.

 

What is the fluorescent stick that came with my meter used for?

Checking Meter Output with the Fluorescent Stick
ECO meters ship with a stick of fluorescent material with which you can check your meter's output response.
    •    With the meter on and outputting data, hold the stick approximately 1/2-in (1 cm) from the lit detectors. Be careful to NOT touch the sensor face, as it scratches easily.
    •    Pivot the stick to parallel with the meter's optics; the output in the  meter's "signal" column should increase to near maximum output as given on the meter's characterization or calibration sheet.
    •    As you move the stick away, the output will decrease.

 

What is the memory capability?

    •    Not included on the "RT" units!!
    •    The memory is stored in "Flash" memory, an integrated circuit chip on the electronic board set.
    •    There is no removable card, no upgrade in memory capacity.
    •    The total sample records available for a single channel ECO = 108,000.
    •    Typically, the ECO output is set to 1 sample/sec.

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.

What type of batteries are in ECO's?


    •    We recommend the use of Lithium batteries in all of our ECO battery units.
    •    There is a very significant battery life increase in comparison with Alkaline cells.
    •    We use Ultralife Lithium +9V batteries.
    •    Ultralife has 3 different part numbers (used with different sales packaging) for the long-life batteries we use in our ECO's:
    ◦    U9VL
    ◦    U9VLX
    ◦    U9VLBP
    •    Ultralife batteries have Aluminum/Mylar housing providing:
    ◦    Protection against humidity and heat from entering the battery. Humidity and heat reduce efficiency and shelf-life.
    ◦    Batteries that are much more leak-resistant.
    •    Ultralife batteries have a 7-10 year shelf-life.
    •    The batteries are customer replaceable with easy access to the battery pack.
    •    The battery pack has 6 batteries: 2 layers of 3 +9V Lithium cells.

Bioshutter II

The Bioshutter II is an autonomous underwater shutter attachment designed for use with Satlantic radiometers. The primary purpose of the shutter is to prevent marine bio-fouling of the sensor optics in moored, time-series application. Copper, and copper-based alloys have long been known to have good resistance against bio fouling and have been used in a diverse variety of commercial applications. Scientists working at the University of California Santa Barbara Ocean Physics Lab under the auspices of the National Ocean Partnership Programs' (NOPP) Ocean System of Chemical, Optical, and Physical Experiments (O-SCOPE) project developed an underwater shutter device for use with instruments such as Satlantic's OCR-500 and HyperOCR series instruments. The Satlantic Bioshutter II device builds upon the success of this instrument by combining an innovative copper shutter and an input power controlled motor drive assembly to ensure robust operation in harsh marine environments.
