1.2 Specifications
1.2.1 Standard Specifications
Object of Measurement: Concentration of oxygen dissolved in solution (water)
Principle of Measurement: Galvanic-cell method
Measurement Range: 0 to 20 ppm, 0 to 20 mg/L, or 0 to 100% (saturation)
Note: The measurement range must be entered through the dissolved oxygen converter.
Resistance Temperture Detector (RTD) :
Pt 1000
Construction:
Sensor unit : Rigid PVC, Stainles steel
O-ring: Nitrile rubber
Permeable membrane: Fluoro-resin [FEP]
Cable shielding : Heat-resistant flexible PVC
Outlet of cable : Polycarbonate resin
Sensor Cable:
Length : 3 m, 5 m, 10 m, 15 m, or 20 m (specified when ordering)
Crimping terminal configuration : Pin-type, M4 Ring-type or Fork-type (specified when ordering )
Weight: Approx. 0.3 kg + 0.12 × N kg N: cable length
(e.g. for cable length of 5 m, approx. 0.9 kg)
Temperature of Solution Under Measurement (SUM) : max. 0 to 40 °C
Flow rate of SUM: No less than 20 cm/s
(recommended to prevent the sensor from trapping bubbles that are
the source of error in measurements)
Pressure of SUM:
Normally : 0 to 30 kPa
Maximum applicable : 100 kPa
[Characteristics]
Repeatability:
0.1 mg/L or 3% FS, whichever is greater (including sensor)
Temperature Compensation Error: Within ±3% FS
(including sensor) for a ±5 °C change in the range of 0 to 40 °C
Response Time : Within 2 minutes (90% response) (including sensor)
