Mini TDGP Submersible Sensor
The Mini TDGP measures the total dissolved gas pressure in liquids. It provides accurate TDGP data and is designed for use in aquaculture, dam spillways, groundwater monitoring, and industrial applications.
Unlike other total gas pressure 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 be used for long term deployments with simple, stable and accurate results.
With periodic membrane cleaning and calibration checks, the Mini TDGP requires minimal maintenance.
