📌 Selection and Use Notes
For DO measurement
Probe preparation: check membrane condition, electrolyte fill and absence of air bubbles before measurement.
Calibration: use air-saturated water for routine calibration and zero oxygen point when required by SOP.
For sample control
Pressure: use automatic barometric pressure compensation and confirm the correct pressure unit.
Salinity: apply manual salinity correction for saline or high-ionic-strength samples.
For GLP / GMP workflows
Traceability: use GLP data storage and GMP logs to support measurement record review.
Export: use USB 2.0 or RS-232 when printer, PC, scanner or autosampler workflow is required.
