Alat Sensor Oksigen Terlarut Dissolved Oxygen Sensor W-DO

Description

User-replaceable DO cap lasts 2 years or more
High accuracy measurements, even without calibration
Get salinity-adjusted DO directly when used with conductivity sensor (W-CT or W-CTD), no need for post-processing
Direct DO percent saturation data, no need for post-processing (when used with MX802)
Easy calibration with included calibration boot – saves time
1” diameter for use in narrow wells (with cable to MX802 above the well)
PVC housing holds up in saltwater

Optical Sensor: (dynamic luminescence quenching)

Measurement Range: 0 to 60 mg/L; 0-600% Saturation

Accuracy:

Out-of-box: ±0.2 mg/L (typical) over the range of 0 to 20 mg/L

±4% over the range of 20 to 60 mg/L

With user calibration: ±0.1 mg/L over the range of 0 to 20 mg/L; ±2% over the range of 20 to 60 mg/L

Resolution: 0.01 mg/L

Sensor Drift: Accuracy is maintained for 2 years; aside from the effects of fouling

Response Time: To 90% in less than 45 sec

DO Sensor Cap Life: 2 years; after this the sensor will continue operate, but possibly with less accuracy

Temperature Measurement/Operating Range: -5 to 50°C (23 to 104°F), non-freezing

Temperature Accuracy: 0.15°C (0.27°F)

Temperature Resolution: 0.01°C (0.04°F)

Response Time: To 90% in less than 15 minutes

Logging Rate: When using this sensor, the maximum logging rate is 1 min

Depth Rating:

IP-68, waterproof to 100 m (328 ft) – must be attached to logger and have DO sensor cap installed

Wetted Materials: Black Delrin®, PVC, EPDM o-rings, rated for saltwater use

Size: To Be Determined
