Photonics for future chemical sensing


SentrOXY aDO series with Protective Cap

Our objective is to offer a versatile, accurate and real-time water quality monitoring and control system that reliably provides actual data and predictions. Our solution achieves this goal while also requiring low power consumption, low costs of ownership, and fair investment costs.

Our DO sensors combine operational flexibility with the latest optical sensor technology to meet the high quality demands of our customers. The available sensor options are innovative devices that measure accurately in even in the harshest aqueous environments.

A key feature of solutions is the integrated Sentro.IO radio-controlled interface. By leveraging passive, function-specific tags or accessories, users can control, calibrate and communicate with the sensors directly.

Sentro.IO eliminates the need to physically disconnect the devices, or to connect them to a computer or control unit, while performing these tasks. This smart, wireless technology saves time and cuts costs.

SentrOxy aDO series
Optical DO sensors for water quality management and aquaculture applications.

SentrOxy aDO-20
The aDO-20 is far more than just an optical DO-Sensor with a digital RS485 interface. The aDO-20 was designed so that it's innovate features are as easy as possible to use.

SentrOxy aDO-50
The aDO-50 is an optical DO-Sensor that enables flexible integration possibilities via parallel digital RS485 or 2x 0/4-20mA interfaces, as well as easy access of functions (e.g., a DCS) for validation. Additionally, it contains integrated control functions, which allow customers to mitigate the development costs of programming thresholds or time-controlled functions. The aDO-50 also allows for direct control of up to two switching actuators. This compact sensor brings you high investment protection and maximum operational flexibility.

SentrOxy aDO-60
Do you want to measure, control switching actuators directly at the measuring point, display the measured values locally and remotely in the control system, and ensure that this all works in parallel? The aDO-60 is your optical DO sensor solution with digital RS485, 2x 0/4-20mA, 2x digital I/Os and many helpful features

SentrOxy aDO-40
The aDO-40 is an optical DO-Sensor with digital RS485 interface that not only makes measurements; it also directly controls up to two switching actuators, e.g. a solenoid oxygen valve, in parallel. The device can be the basis for the most optimized, fully automatic, autonomous oxygen control at your tank or it can send signals via a signal lamp to let your employees know whether manual feeding is possible.
