Monitor your effluent for a variety of parameters.
Wastewater, or effluent, that is discharged into local water systems, including sewers, must adhere to trade effluent controls set by the government. It is essential to test for a number of parameters in order to keep the public safe as well as preventing damage to wastewater treatment processes and the environment.

HI6000 Series Benchtop Meters
Introducing our NEW Advanced Benchtop Meter Series! Reliable, accurate, consistent. Choose from 3 models: pH/ORP, Conductivity, and DO.
Measuring Dissolved Oxygen with Optical Technology
Wastewater treatment plants rely on bacteria to break down the organic compounds found in water. If the amount of dissolved oxygen in the wastewater is too low, these bacteria will die and septic conditions will occur. The amount of DO must be consistently monitored to ensure proper waste treatment.
Subjective Water Clarity
Turbidity is an optical measurement that indicates the presence of suspended particles. It's measured by shining light through a sample, and quantifying the suspended particle concentration. The more particles that are in a solution, the higher the turbidity. Drinking water and municipal wastewater plants often remove turbidity with a combination of sand filtration, settling tanks, and clarifiers.
