Introduction
The DO30G Dissolved Oxygen Sensor bases its principle of measurement on the galvanic-cell
method. The sensor is specifically suited for continuous measurement of oxygen dissolved in
water.
Topics and information that need your special attention in handling the product are given in the
text of this manual along with cautionary notes, such as a warning or caution, depending on their
importance. Strictly observe these items from the standpoint of safety and prevention of equip-
ment damage. For a notation, such as a warning also indicated on the product, there is an alert
mark in the manual.
1. Confirming the Specifications
The standard specification DO30G dissolved oxygen sensor is used to build the dissolved oxy-
gen metering system.
The DO30G sensor cable has the prescribed length. The configuration of the crimp-on terminals
are either pin-type, M4 ring-type or fork-type.
Upon arrival of the purchased product, carefully unpack it and make sure the product is com-
pletely free from any damage that may have occurred during transport. Also check the model
code indicated on the nameplate attached to the sensor cable to make sure that you received the
