1.2.1 Turbidity Sensor 4296

Turbidity Sensor is encapsulated in a Titanium housing and are available in three depth ratings

300-meter, 3000-meter and 6000-meter. The sensor is designed for use on SeaGuard platforms

but may also be used on cable. Standard version has AiCaP and RS-232 output. Please note that

the lemo plug used for this sensor are not a 1 to 1 plug. This means that e.g. pin 1 on sensor are

connected to pin 8 on cable.
