Sea-Bird Scientific is excited to offer a limited-time trade-in program for customers with a SUNA V1 or ISUS nitrate sensor. Eligible participants will receive a trade-in credit toward the purchase of a SUNA V2, now available at a dramatically reduced price.

  • Accuracy and stability over a wide range of environmental conditions
  • Adaptive sampling intelligence
  • Universal real-time nitrate processing algorithm
  • 10 optical pathlength
  • Serial data output
