AML Metrec•X

Ideal for Real-Time Multi-Parameter Work and In-Situ Deployments

Metrec•X is a real-time, multi-parameter instrument that allows you to change the instrument’s sensor load, in-the-field and on-demand. Metrec•X can accommodate as many as five Xchange™ sensor-heads on the end-cap, allowing you to configure the focus of your research on an application by application basis. With Metrec•X, conductivity can be swapped for sound velocity; shallow pressure sensors can be swapped for deep; and temperature range can be extended or tightened, as needed. One instrument meets multiple deployment requirements.

Field-swappable sensors also streamline recalibration: instead of sending the entire instrument back to a recalibration centre, calibrated sensor-heads can be sent to the instrument. Changing sensors is easy: simply unscrew one sensor-head and replace it with another.

Metrec•X is ideal for long term, in-situ deployments with UV•Xchange for biofouling control. By eliminating biofouling-induced drift, UV•Xchange allows sensors to perform to their full potential on in-situ instruments. Install UV•Xchange on a Metrec•X for a high performance in-situ CTD.

Available Sensor-Heads

X•Series instruments are compatible with our Xchange™ sensor-heads:

Sound Velocity: SV•Xchange™
Conductivity: C•Xchange™
Temperature: T•Xchange™
Pressure: P•Xchange™
Turbidity: Tu•Xchange™
Sensor-heads are ordered separately. Read more about compatible sensors here: AML Sensors
