Pro-Oceanus Mini-TDGP

measure total dissolved gas pressure


  • A Sensor for Total Dissolved Gas Pressure
  • Most Accurate and Stable Submersible Sensor
  • Suitable for Scientific Research and Industrial Purposes

The Mini TDGP measures the total dissolved gas pressure in liquids. It provides accurate TDGP data, designed for use in aquaculture, dam spillways, groundwater monitoring, and industrial applications.

Unlike other total gas pressure (TGP) probes, the Mini TDGP is not affected by increasing hydrostatic pressure. The sensor’s semi-permeable membrane is also biofilm resistant.

The rugged Mini TDGP sensor is designed for use in water, oil, and contaminated mixtures. The probe combines an oil resistant membrane with a compact pressure sensor that provides quality TDGP data. The Mini TDGP sensor can provide long term deployments with simple, stable and accurate results.

With periodic membrane cleaning and calibration checks, the Mini TDGP does not require replacement parts or need frequent and tedious maintenance.
