Online Dissolved Oxygen Analyzer

在线溶解氧分析仪

Aeration basins, deaerators, fermenters and fish tanks each need oxygen kept in range, and this online analyzer covers 0–20 mg/L, with a 0–2000 μg/L trace option for feedwater. Accuracy is ±0.1 mg/L or ±1 % of reading. Standard process limit is 0–50 °C, optionally 130 °C, at up to 10 bar.

Measuring range: 0–20 mg/L (0–200 % sat.)
Trace range option: 0–2000 μg/L
Accuracy: ±0.1 mg/L or ±1 % of reading
Resolution: 0.01 mg/L (1 μg/L trace)
Response time (T90): <60 s
