SMB-001 Deep C Meter 300 AD Manual
5. Probe unit components
The Deep C Meter 300 AD™ utilizes the popular Polatrak ROV-II™ tip contact probe.
More detailed information can be found in the ROV-II operation manual Doc. No. 354-MN01-ENG.
5.1.
Housing -
The housing provides protection to the reference electrode elements. It is made from
a rugged thermoplastic and is designed to fit the compliant tee handle mount for convenient
manipulator mounting. The holes in the side allow the body to become free-flooding and are specifi
-
cally engineered to allow for accurate potential measurements.
CAUTION
Do not cover or modify the existing holes or add additional holes in the body.
5.2 Tail assembly -
The tail assembly attaches to the main body section with two (2) stainless steel
¼”-20 allen head cap screws. The ROV-II flying lead passes through this unit and has a spiral strain
relief fitting. The tail unit includes one male connector for the contact tip and two female connectors
for each of the reference electrodes.
5.3 Nose cone w/ tip -
The nose cone assembly is screwed into the main body section. The cone
houses the replaceable contact tip; it also includes the female connector that attaches to the male
pin on the extension cable from the tail unit. Tips are made from stainless steel and plated with
nickel; the nose cone is fabricated from a rugged thermoplastic.
5.4 Reference electrode element -
Two plug-in silver/silver chloride elements are included.
Electrode elements are accurate to ± 5 mV. See the operations and maintenance section for instruc-
tions on electrode replacement.
CAUTION
Never handle electrode elements with bare hands or expose elements to a liquid other
than fresh water or seawater, as permanent damage may result.
