Optical DO

Shrimp ponds are among the harshest environments a dissolved oxygen (DO) sensor will ever see. High organic loading, aggressive aeration, biofilm accumulation, sunlight-driven algal blooms, and hurricane-season temperature swings combine to punish membrane-based galvanic probes. The result, in most shrimp operations, is a familiar failure signature: an oxygen probe drifting silently for two weeks, then…
