Y552-B COD Sensor Calibration
Required equipments and raw materials
required equipments: three 250ml brown bottles, one 1L brown bottles, one power adapter, one USB converter, 10m cable.
raw materials: 150mg/L standard solution, 450mg/L standard solution, distilled water or deionized water.
Calibration steps
There
are two methods of user calibration for the COD sensor: 1-point calibration and 2-points
calibration.
1-point calibration was done in 150mg/L standard solution, 2-points calibration was done in 150mg/L and 450mg/L standard solution.
1-point calibration step (change the K value)
Step 1:Put the COD sensor into deionised water. Open the SmartPC software and click "self-calibration". Wait for the self-calibration value to stabilize.
Step 2:Then put the COD sensor into 150mg/l standard solution, click "1 Point". Wait for the 1 point calibration value to stabilize.
2-points calibration step (change the K and B values)
Step 1:Put the COD sensor into deionised water. Open the SmartPC software and click "self-calibration". Wait for the self-calibration value to stabilize.
Step 2:Then put the COD sensor into 150mg/l standard solution, click "2 Point". Wait for the calibration value to stabilize in the first solution.
Step 3:Then put the COD sensor into 450mg/l standard solution, Wait for thecalibration value to stabilize in the second solution.
