compensation

Method 1: For NaCl or general solutions use

NaCl

compensation

2%/°C

Method 3: Existing matrix
Data corresponds to the following solution

Matrix temperature compensation (existing data)
*SERV 22

Method 4: Where present matrix data does not exist,

for example, when the temperature coefficient

is

not

constant

α you can create a user matrix.

Calibration in Air (Air Set)

(correct zero offset

due to leakage resistance)

Calibrate in actual

measured solution

User-defined matrix temperature compensation
*SERV 23-28

Method 2: For other temperature compensation coefficients
