Aquasend’s miniDOT Clear Logger effective in hydroponics and aquaculture 

Aquasend, a water quality monitoring company, said a large-scale hydroponics and small-scale aquaculture farmer used its miniDOT Clear Logger and reported accurate and economical continuous monitoring.

The miniDOT Clear Logger’s clear plastic housing contains a real-time LCD of dissolved oxygen (DO) and temperature levels in virtually any water system. Its oxygen-sensing optode uses a fluorescence method to determine DO concentrations and its custom sampling frequency can be set anywhere from once per minute to once per hour, with data recorded to the logger’s internal SD card. It’s powered by two AA lithium batteries for easy in-field replacement.

In one hydroponics operation, the farmer explained that two miniDOT Clear Loggers helped him prove a long-held suspicion of cycling inadequacies. 

“By placing the loggers on opposite ends of a single tank, the farmer demonstrated inconsistencies in the water quality that had not been reflected by the facility’s fixed monitoring system,” a post from Aquasend reads.

The farmer also secured the miniDOT to one of the many slow-moving rafts hosting seedlings. He was able to accurately monitor water conditions where they mattered most to the plant’s growth and further refine the facility’s production process.
