Included / typical delivery (reference)
- PRO6163 polarographic DO electrode kit (with membrane covers)
- Zero oxygen calibration solution
- Dissolved oxygen electrolyte
- 3 pcs electrode membrane covers
- Touch pen
- COLO-6 electrode stand
Options & notes
| probe consumables | Membranes and electrolyte are consumables; keep spares for uninterrupted operation. |
| calibration practice | Use air-saturated water for routine calibration; use a zero oxygen point when required by SOP or validation. |
| reporting | Export GLP results and logs via USB or integrate via RS-232 for documentation workflows. |
| configuration notice | Final delivered configuration may vary by region and quotation package; specifications may change without notice. |
Practical operation notes
| topic | recommendation | note |
|---|---|---|
| probe preparation | Ensure membrane and electrolyte are correctly installed; remove air bubbles and verify stability before measurement. | Polarographic probes require correct membrane condition for stable results. |
| calibration | Calibrate with air-saturated water for routine use; apply zero oxygen calibration when SOP requires. | Calibration reminder helps keep measurement traceability. |
| compensation | Keep ATC enabled; use barometric compensation and set the correct pressure unit; apply salinity factor correction for saline samples. | Pressure and salinity significantly affect DO results. |
| data management | Use GLP storage (1000 groups) and export logs/results via USB or RS-232 for reporting. | GMP logs support tracking and analysis of stored data. |
