| Monitor for supersaturated waters with one unit! Total dissolved gas pressure is an important parameter for monitoring water quality effectively. When the total pressure of all the gases in the water exceeds the ambient atmospheric pressure at the water surface, supersaturation exists. The effect of excessive supersaturation on fish has been well documented, and if supersaturation exceeds the established safe levels, massive fish kills can occur. Supersaturation can be caused by numerous man made and natural sources Dam spillways which allow the discarge to plunge deeply into the receiving water Heated discharge of thermo-electric power plants can raise the temperature of the receiving water to a point of supersaturation Faulty water pumps used in aquaculture recirculatory systems can cause air entrainment if a leak occurs on the suction side of the pump Naturally high levels of nitrogen can be found in well water Algae blooms can cause increased levels of gas in the water Precautions can be taken to keep supersaturation within safe levels, but the accurate in-situ gas measurements must be made to determine if remedial action is effective. The TDG Sensor makes this measurement quick and easy. | |||||||||||||||||||||||||||||||||||
