Abstract |
The Hach DR-EL colorimeter has been observed in a number of wastewater treatment plant laboratories about the state where they are presumably being used for routine laboratory analyses. The Hach DR-EL, will be an excellent contribution to wastewater treatment plant laboratories if its presence encourages performance of routine monitoring of water quality. In a special problems summer course, graduate students in Sanitary Engineering at New Mexico State University have evaluated the accuracy and precision of tests performed with the Hach DR-EL. |
