Mini TDGP Dissolved Gas Sensor

The Mini TDGP is a miniature submersible sensor that provides highly accurate measurement of the total dissolved gas pressure in liquids. It features biofilm resistance and is unaffected by increasing hydrostatic pressure, and can be provided with a plastic housing for deployment at depths of up to 600 meters, or in a rugged titanium enclosure for depths of up to 6000 meters.

The sensor is available with a variety of measurement range options, and can be customized by Pro-Oceanus to suit specific requirements. It includes a built-in data logger and controller with 2GB of flash memory for storage.

The Mini TDGP can be deployed as an autonomous standalone unit or integrated into platforms such as ocean gliders and AUVs, and is ideal for a wide range of applications including aquaculture, groundwater and wellwater monitoring, gas supersaturation monitoring, and measurement of gas pressure in water wells during pumping.
