Weekly / during deployments
- Clean biofilm from sensors with a soft brush
- Check DO sensor cap for scratches
- Wipe the turbidity window
Monthly / quarterly
- Replace pH reference electrolyte or check junction
- Review calibration history for drifting slopes
- Update firmware as advised
Annual

SAFETY
Safety precautions
Before you work on the Multiparameter meter
- Follow fieldwork safety rules near water: work in pairs and wear a life jacket where needed.
- Wear gloves when handling wastewater; it may contain pathogens.
- Calibration standards and electrode filling solutions are mild irritants; avoid skin and eye contact.
- Dispose of used buffers and standards as per site procedure.
