EN-10 Analyzer and Bench Meter
2.3 Connect the pH and conductivity electrodes
The following graphics demonstrate sockets available for pH and conductivity
measurement. Some models have fewer sockets than others, depending on the
measurement modes the meter/analyzer support.
a-AB33M1
There are two sockets for pH electrode, the “pH/mV” socket and the “Temp” Socket.
One socket for conductivity electrode, the "COND" socket.
a-AB33PH / a-AB41PH
There are two sockets for pH electrode, the “pH/mV” socket and the “Temp” Socket.
Note
: for 2-in-1 pH electrode, you only need to connect it to the pH/mV socket, while for
other electrodes, you need to connect to both the pH/mV and Temp socket.
a-AB33EC
There is one socket “COND” for conductivity electrode.
