- Carrying case
Options & notes
| calibration practice | Use air-saturated water for routine calibration; use a zero point when SOP/validation requires. |
| pressure & salinity | Set the correct pressure unit and apply salinity correction for saline samples to maintain accuracy. |
| power management | Use Auto Shutdown to extend battery service life during fieldwork. |
| 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 | Inspect membrane condition, electrolyte and stability before logging results. | Polarographic probes require correct membrane/electrolyte condition for stable results. |
| calibration | Calibrate with air-saturated water for routine use; apply zero oxygen calibration when required. | Supports air-saturated water or zero point calibration. |
| compensation | Use ATC (or MTC when needed); apply barometric pressure and salinity correction for best accuracy. | Pressure and salinity influence DO and % saturation calculations. |
| data management | Store GLP groups and export results via USB for reporting and documentation. | USB supports PC/printer connection for documentation workflows. |
