APT4000PH
Intended use
The APT4000PH is used for pH/mV, ORP, and temperature
measurement in industry, environment, food processing and
sewage treatment.
The rugged molded enclosure can be fixed into a control panel
or mounted on a wall or at a post. The protective hood provides
additional protection against direct weather exposure and
mechanical damage.
The analyzer can be easily replaced and it accepts commercially
available electrodes with a nominal zero point at pH 7 and
DURAFET II electrodes.
