Total Dissolved Gas (TDG) Sensor
Total Dissolved Gas (TDG) is the sum of the partial pressures of all gases in a water sample. Normally, the sum of gas partial pressures will be about one atmosphere (15 psi) for any water that is exposed to the atmosphere. The partial pressure of each gas will be the same as that’s gas’s contribution to atmospheric pressure, i.e. about 20% oxygen, 79 % nitrogen, and 1% trace gases. ...
