Dissolved Oxygen Sonde: Rinko EC

PRODUCT OVERVIEW
Aquatic eddy covariance method is a powerful technique to measure benthic fluxes. The RINKO series is based on the optical (phosphorescence) principle which is now widely known as a remarkably fast response oxygen sensor with high accuracy. As a new member of the RINKO family, the robust RINKO EC (model name: ARO-EC) is designed for aquatic eddy covariance measurements. The response time of the RINKO EC oxygen sensing foil is less than 0.5s (90%, from air to water at 25 °C). The foil life-time is more than 200h, which enables at least 1 week of continuous measurements of dissolved oxygen. Moreover, the foil can be replaced easily by users. The RINKO EC is an advantageous tool for eddy covariance measurements in many aquatic environments.
KEY FEATURES
