Penting karena :
In a nephelometer, light reflects off turbidity particles in the water and is measured by a photomultiplier tube.
The amount of light reaching the photomultiplier tube is proportional to the amount of turbidity in the sample water.
Menggunakan cakram Secchi ( Secchi disk) untuk mengukur transparansiThe disk is lowered until it is no longer visible. That point is the Secchi disk depth.
Using a transparency tube(A) Prepare the tranparency tube to take a reading. Place the tube on a white surface and look vertically down the tube to see the wave pattern at the bottom.(B) Slowly pour water sample into the tube stopping intermittently to see if the wave pattern has disappeared.
