PyroScience offers one-device solutions for oxygen, pH and temperature measurements in the lab (FireSting-PRO) and underwater (AquapHOx). The revolutionary AquapHOx technology includes long-term loggers for stand-alone operation during long monitoring approaches and real-time data transmitters for ultra-fast water column profiling. The flexible deep-sea multi-analyte logger/transmitter can operate down to 4000 m water depth. They are compatible to various optical underwater sensors from PyroScience: simply exchange the sensor head, choose between different analytes (pH, O₂ or T) and sensor formats, and measure in open ocean, the deep sea, coastal ecosystems, rivers, lakes and water bodies.
