Underwater Oxygen and pH Meters

PyroScience the new, compact and easy-to-operate AquapHOx platform is a flexible solution for many underwater Oxygen and pH measurment applications. Besides stand-alone loggers with internal data storage for long term deployment, there are also transmitters for fast sampling and easy integration into existing set-ups utilizing the integrated analogue outputs.
The oxygen and pH loggers and transmitters are available with a titanium housing for subsea applications up to 4000m. These devices are highly flexible concerning choice of analyte and sensor format as O2, pH and optical temperature sensors can be connected.
For applications in shallow water, Oxygen, pH and temperature loggers and transmitters with a POM housing are available which can be deployed up to 100m. These devices are dedicated to one analyte but with the same flexibility concerning sensor format (e.g. caps or fibre based sensor).
