Connecting the Cable (Pro20 Only)
The Pro20 is designed for field and laboratory use. It is compatible with
two different cable options:
1. The field rugged cable is available in standard lengths of 1, 4, 10,
20, 30, and 100 meters with special lengths available between 30
and 100 meters. This cable has a built in temperature sensor and
includes a port for the dissolved oxygen sensor.
2. The ProBOD is a 1 meter probe/cable assembly with built in
Polarographic dissolved oxygen and temperature sensors. It has
an AC powered motor for sample stirring and is designed to fit into
a 300 ml BOD bottle.
To connect the cable, align the keys on the cable connector to the slots
on the instrument connector. Push together firmly and then twist the
outer ring until it locks into place (figure 4). This connection is water-
proof.
Figure 4, Note the keyed connector.
When disconnected, the sensor and cable’s sensor connectors
are NOT water-proof. Do not submerge the cable without a
sensor installed. When disconnected, the cable’s instrument
connector and the connector on the instrument maintain a
waterproof, IP-67 rating.

MEMBRANE INSTALLATION
The dissolved oxygen sensor is shipped with a dry, protective red cap
that will need to be removed before using. It is very important to put a
new membrane with electrolyte solution on the sensor after removing
the red cap.
