AquaSense-DOX

Industrial online dissolved-oxygen analyzer with fluorescence DO probe, wall-mount cabinet, touchscreen controller, RS485 / Modbus RTU output, and on-board recording for continuous process and environmental monitoring.

AquaSense-DOX is the industrial analyzer-cabinet variant of the AquaSense-DO platform. It pairs the AquaSense fluorescence-lifetime DO probe with a wall-mounted controller, a colour touchscreen, RS485 / Modbus RTU output, and on-board data recording — delivering a complete continuous-monitoring system for water-treatment, environmental, and industrial-process water.

Continuous Logging

On-board data recording with remote review over the digital bus.

Wide Application Fit

Power, water treatment, environmental, food, and aquaculture process use.

Overview

AquaSense-DOX is the industrial online-analyzer variant of the AquaSense dissolved-oxygen family. It combines the same fluorescence-lifetime DO probe used in AquaSense-DO with a wall-mount controller cabinet, a colour touchscreen, RS485 / Modbus RTU output, and on-board data recording — turning the probe into a complete continuous-monitoring instrument suitable for plant rooms, control panels, and outdoor enclosures.

The plug-and-play probe interface and stored calibration on the sensor make routine servicing fast: a calibrated probe can be swapped in without recalibrating the controller. Standardised digital outputs keep the analyzer compatible with PLCs, SCADA, and third-party telemetry, and on-board logging with remote review supports compliance reporting and process review.

Typical deployments include municipal water-treatment lines, environmental monitoring stations, reservoirs and lakes, aquaculture process water, and a wide variety of industrial process flows — power, chemical fertiliser, metallurgy, pharmaceuticals, food and beverage, and similar — where reagent-free, low-maintenance DO measurement is preferred.
