Shallow water oxygen OEM meter for convenient and fast deployment

Pyroscience recently launched the APHOx-S-O2, a compact underwater sensor for dissolved oxygen measurement in shallow water. The device uses a robust optical principle based on an oxygen-sensitive luminescent dye, and is factory calibrated for temperature-compensated oxygen measurements.

Designed specifically for measurements in aquacultures and surface waters, the APHOx-S-O2 features a corrosion and biofouling-resistant copper alloy housing, which enables operation at up to 50 meters depth. The meter also provides an RS485 interface and 4 analogue outputs (2x 4-20 mA. 2x 0-5V) for easy integration into various control systems.

With its innovative REDFLASH technology, the APHOx-S-O2 impresses with its high precision, high reliability, low cross-sensitivity, and fast response times. The REDFLASH sensor materials are activated with red light and show an analyte-dependent luminescence in the near-infrared (NIR) range, which significantly reduces interference caused by auto-fluorescent samples.

In addition to the digital interface and protocol, a broadcast mode can be configured where the device measures in a pre-defined interval and provides real-time measurement results at the analogue outputs, without requiring digital communication.
