Quick Overview

Suitable for depths to 13,000 feet, the Merlin can monitor up to 10 analogue, a single K-Type and serial inputs with the memory capacity of 10 million readings. The power efficient Merlin can also display its current real-time readings via a single or dual back-lit display configuration which can be clearly view with a ROV. Record pressure, flow, temperature, acceleration, light and much more makes the Merlin an ideal solution to your subsea monitoring requirements.
