Smart Phone / App Data Logging
In addition to a scientific analyzer for educational/teaching activities, the smartphone kit is an ideal choice for measuring Biochemical Oxygen Demand (BOD)/Chemical Oxygen Demand (COD) since a quick test of the oxygen content in a laboratory is a guarantee for the dependable data accuracy.

Sensor Calibration:
1) One-point calibration: 100% saturation (air-saturated water or water-saturated air)
2) Two-point calibration:
a) 100% saturation (air-saturated water or water-saturated air)
b) 0% saturation (zero oxygen water).
Sensor Compensation:
1) One-point calibration: 100% saturation (air-saturated water or water-saturated air)
2) Two-point calibration:
a) 100% saturation (air-saturated water or water-saturated air)
b) 0% saturation (zero oxygen water).
Salinity Compensation:
1) Oxygen concentration:
1) Temperature: 0-55°C automatic compensation
2) Pressure: 0-150kPa manual or program compensation
3) Salinity: 0-50 ppt manual or program compensation.
Sensor measurement accuracy：
1) Oxygen concentration:
a) ±0.1mg/L (0-10mg/L) or saturation ±1.0% (0-100%)
b) ±0.2mg/L (10-25mg/L) or saturation ±2.0% (100-250%)
c) ±0.3mg/L (25-50mg/L) or saturation ±3.0% (250-500%)
d) ±1ppb (0-2000ppb)
2) Temperature: ±0.1°C
3) Pressure: ±0.2kPa
4) Resolution:
a) 0.01mg/L (conventional and large-range 0-50mg/L)
b) 0.1ppb (small-range 0-2000ppb)
