The TDG300E (Total Dissolved Gas Sensor) is the perfect instrument for monitoring water quality.
To monitor water quality effectively, total disslved gas pressure is an important parameter which
needs to be taken into account. Supersaturation exists when the total pressure of all the gases in
the water exceeds the ambient atmospheric at the water surface. The effect of excessive supersaturation
on fish has been well documented, and if supersaturation exceeds the established safe levels, massive
fish kills can occur. Accurate gas measurements can be made by the TDG 300E to determine whether
remedial action needs to be taken.
