MetrecXL 12h web


A multiparameter sonde for measuring more parameters for longer periods of time.

Expand monitoring timelines and collect higher quality data while reducing maintenance costs. AML’s largest instrument platform is designed for long term environmental monitoring, with all sensors protected against biofouling by adding our UV•Xchange™. By eliminating biofouling-induced drift, UV•Xchange™ allows sensors to perform to their full potential on in-situ instruments. Turner Designs Cyclops-7F sensors install directly onto the sondes for seamless integration of two proven solutions. 

Ideal for surface monitoring or integration into buoys or other platforms where biofouling is an extreme challenge. Depth rated to 500 m.  A copper-nickel alloy cage option (shown) is available for incidental biofouling protection. 

Take advantage of Xchange™ sensors’ field swappability with Metrec•XL: Configure the focus of your research on an application by application basis. One instrument meets multiple deployment requirements.
