AquaGo-DO

Portable optical dissolved oxygen meter with a replaceable fluorescence cap, one-touch measurement, e-ink display, and long standby time for field spot-checks.

AquaGo-DO is a handheld optical dissolved oxygen analyzer designed for fast, low-effort field measurements. The fluorescence sensing cap on the probe is field-replaceable, the e-ink display gives a paper-like reading experience that stays clear in direct sunlight, and a one-touch measure key makes data collection genuinely fast.

AquaGo-DO Overview

AquaGo-DO is the handheld variant of the AquaSense dissolved-oxygen family. The fluorescence-lifetime optical probe consumes no oxygen and tolerates wide flow conditions, while the handheld unit adds a one-touch measure key, an e-ink display, and an integrated backlight for night work.

The replaceable sensing cap means the probe can stay in service for years with low maintenance overhead. The unit ships with submersible cable lengths suitable for spot-checks in aquaculture ponds, surface water, drinking water, and process samples, and pairs naturally with AquaSense-DO probes used elsewhere in the same monitoring program.
