Initial accuracy: 

DO: ±2% of measured value or ±2.0 μmol L^-1 (calibraƟon range: 3 to 30 °C)

Temperature: ±0.01 °C



Sample-based drift: ±5% of measured value or ±5.0 μmol L^-1 / 4.000.000 samples

Pressure effect: ±2% of measured value or ±2.0 μmol L^-1 

Temperature effect: ±2% of measured value or ±2.0 μmol L^-1

Response time (63%) (at 25 °C. typical)

DO < 1 s (in water)

Temperature < 1 s (in water)

Representative output parameters: DO in μmol L-1. Temperature in °C. Engineering values of DO and temperature. Number of LED emission times. etc.
