WQMS Proteus For (Sparing)

Chemical Oxygen Demand (COD) (CAL-COD)

• Parameter: COD mg/l

• Range: 0 - 4000 mg/l

• Resolution: 0.01 mg/l

• Accuracy: ±5 % of reading*

• Comments: Local site calibration can improve accuracy.

pH (P-S-PH)

• Parameter: PH

• Range: 0 to 14 units 0.01

• Resolution: ±0.1

• Accuracy: within 10°C of calibration, 0.2°C otherwise

• Comments: Refillable reference electrode; corrected for temperature; typical sensor life > 4 years.

Amoniak - nh4 (P-S-ISE-NH4)

• Range: 0 to 100 mg/l as nitrogen

• Resolution: 0.1

• Accuracy: ±5 % or 2 mg/l

• Comments: Corrected for ionic strength (via conductivity readings);

the accuracy specification relies on non-trivial maintenance practice and frequent calibration near the temperature of measurement;

ammonium and nitrate require tip replacement every 3 - 6 months. Please contact us for applications >10 m.

Total Suspended Solid (TSS) (CAL-TSS)

• Parameter: TSS

• Range: 0 to 500 mg/l

• Resolution: 4 digits with maximum of two decimals

• Accuracy: ±2 % of reading or 0.2

• Comments: Calculated using the correlation between turbidity and a sediment standard or sample. Local calibration can be applied.

Debit (DEPTH) (P-S-DEP)

• Parameter: Depth

• Range: 0 to 25 m; 0 to 200 m

• Resolution: 0.01

• Accuracy: ±0.05 m; ±0.4 m

• Comments: Conductivity sensor fitted for Salinity
