Measurement
1. Use ISA in all solutions for measurement. Use a ratio
of 1:50 (2% ISA to Solution).
2. Do not touch the PVC membrane with your fingers
3. Rinse the electrode with DI water, blot dry. Do not rub
dry.
4. Connect the sensor to the USB or WIFI or Viewer
module and to PC or battery.
5. Put the electrode in the solution for measurements
6. Wait until value is stable.
Electrode storage
Short term (overnight or weekend):
Rinse the electrode thoroughly with deionized water and
place the tip in a diluted standard solution (around 10
ppm) between measurements.
Long term:
Rinse the electrode thoroughly with deionized water and
blot dry. Attach the hard plastic protective electrode cap
again to protect the sensing element.
