The AQ2 1250m is a calibration-free solid-state pH and temperature sensor rated to 1250 m. It was previously called the OC1250. It calibrates itself in the water and suits subsea vehicles, buoys, moorings and research platforms.
It is pressure tested to 1.5 times its depth rating. It connects with a SubConn MCBH6M connector or a pigtail, and SubConn cables come in 1, 5, 10, 30 and 50 m lengths.
A dedicated spare transducer is available for the 1250 m model, as is a submersible 4 to 20 mA or 0 to 5 V converter rated to the same depth.
