“Bulkhead” refers to the single-pin connector at the end of the probe/cable
assembly where the dissolved oxygen (Do) sensor is installed (figure 3). The
conductivity and temperature sensors are located above and next to the bulkhead
respectively and are not user-replaceable.
i
When a dissolved oxygen sensor is not installed in the cable, the sensor
and cable’s bulkhead connectors are not water-proof. Do not submerge
the cable without a sensor installed. Submerging the cable without a
sensor installed may cause permanent damage to the cable that is not
covered under warranty.
