From Classic to Cutting-Edge - ECO V2 Trade-In Program

Posted on 05.13.2026

For years, the  ECO Classic has been a trusted optical sensor for researchers and professionals seeking reliable optical sensor data in the field. Now, for a limited time, we’re offering an exclusive trade-in credit toward the purchase of the next-generation ECO V2, designed to deliver greater precision, expanded capabilities, and seamless integration into your research workflow. Whether you’re using an ECO Classic or a fluorometer from any manufacturer, this is your opportunity to upgrade at a reduced cost while modernizing your sensing capabilities. 

How it Works

If you purchase through a local distributor: Contact your third-party distributor to initiate a trade-in. Click here if you’re unsure who your local distributor is.

If you purchase directly from Sea-Bird Scientific: Email your Sea-Bird Scientific sales representative or send us an email at sales@seabird.com.

Receive a personalized quote from your local distributor or Sea-Bird Scientific representative with your trade-in credit applied.

Your local distributor or Sea-Bird Scientific sales representative will provide instructions on how to send us your trade-in instruments.

Once we receive, review, and accept your item, you will be credited for the trade-in value!

 

All the Reasons to Trade In 

  1. Save with Trade-In Credit: Receive credit toward your ECO V2 purchase when you trade in your ECO Classic or any third-party fluorometer.
  2. Modernize Your Research Tools: Upgrade to a sensor designed for today’s demands - with greater precision, flexibility, and integration.
  3. It’s Good for the Planet and the Science Community: When you trade in your ECO Classic or fluorometer from another manufacturer, you’re not just upgrading your technology, you’re supporting a more sustainable future. All returned instruments will be considered for donation or responsibly recycled, reducing electronic waste and helping us minimize environmental impact.

ECO V2: Next-Generation Optical Sensor Series

The ECO V2 Series builds on the legacy of the ECO Classic with powerful new features:

  • High Dynamic Range – One range that covers all natural waters, reducing the number of sensors needed
  • User-friendly Software – Compatible with Windows and Mac via UCI
  • Advanced Data Logging – Higher resolution, faster data-handling
  • Extended Deployments – Optional battery packs and active and passive anti-fouling technologies for up to 6000 meters
  • Onboard QA/QC – Ensure consistently accurate data
  • Configurable Output & Baud Rate – Tailor settings to your workflow
  • Improved Battery Life – Interchangeable with the SBE 37 and easier to replace than the ECO Classic batteries

QUESTIONS ABOUT TRADING IN?

We've got answers.
Will you take another manufacturer’s product for trade in?

If you have a fluorometer or scattering sensor from another manufacturer that you no longer use/want, it can be used as a trade in to receive credit for a new ECO V2 sensor.

What condition does my ECO Classic or fluorometer need to be in to qualify?

We will accept your ECO Classic or fluorometer in any condition – working or not. No need to worry about wear and tear. 

Can I trade in multiple instruments for more than one ECO V2?

This promotion is limited to one trade-in discount per ECO V2 sensor, regardless of how many instruments you send in at one time for this program. However, there is no limit to the number of ECO Classics that can be traded in for ECO V2 sensors. For example, if you send in 5 ECO Classics, you are eligible for up to 5 ECO V2 sensors with this trade-in discount.

Can I trade in a WETStar Fluorometer?

Yes, we are accepting WETStar fluorometers or any other third-party fluorometer or scattering sensor.

What will you do with my old instruments?

Based on the condition, we'll responsibly recycle your instruments or donate them to the local marine science community for educational purposes.

When will I receive my new ECO V2?

Your new ECO V2 will ship after we receive your trade-in equipment, and you’ve accepted a quote from our sales team. This ensures a smooth and efficient trade-in process.
