Where:
T
C
= Temperature coefficient
C
TA
= Conductivity at Temperature A
C
TB
= Conductivity at Temperature B
T
A
= Temperature A
T
B
= Temperature B
1.
Press and hold the
o
C
key for 3 seconds to enter the temperature setting.
2.
Press the
or
key to set the temperature to 25° C.
3.
Place the electrode into the sample solution A and record the temperature value T
A
and conductivity value C
TA
.
4.
Condition the sample solution and electrode to a temperature that is about 5
° C to 10
° C different from T
A
. Record the temperature value T
B
and
conductivity value C
TB
.
5.
Calculate the temperature coefficient according to the formula above.
