The DA series of <strong>pH</strong> <strong>and</strong> <strong>ORP</strong> electrodes<br />
are designed to solve operational problems<br />
when stary electrical voltage <strong>and</strong> electrical<br />
ground loops are present in solutions.<br />
Installation with plastic tanks <strong>and</strong> piping are<br />
very susceptible to ground loop problems<br />
because of the non-conductive nature of the<br />
plastic. Motors from pumps or mixers <strong>and</strong><br />
even conductivity electrodes mounted near<br />
<strong>pH</strong> <strong>and</strong> <strong>ORP</strong> electrodes can leak voltage into<br />
the solution to be measured. This voltage<br />
damages the reference part of electrodes<br />
giving erroneous readings <strong>and</strong> leading to<br />
short service life. The DA electrodes reduce<br />
ground loop problems using a solution<br />
ground rod that is fed into an internal batterypowered<br />
(2 year battery life) differential<br />
amplifier: the <strong>pH</strong> <strong>and</strong> reference electrodes<br />
are measured against a ground electrode,<br />
insuring a steady <strong>and</strong> stable signal. An<br />
additional benefit of the amplifier is that it<br />
allows long cable runs over 100m (330 ft.).<br />
