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, SUS304
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:
Narmally : 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)
