With so many variables affecting your water quality management needs, a one-size-fits-all sampler isn’t enough. With Hach’s Sigma 900 Series, you have a full range of options.
If you simply need to obtain a repeatable sample volume at a timed interval or after a predetermined volume of flow, the 900 is your answer. However, should you be required to sample for regulatory compliance, monitor combined sewer overflows or storm water outfalls, or conduct biomonitoring or water quality research, look no further than the advanced technology of the 900 MAX.
Both of these controllers are available in a portable, refrigerated, or all-weather refrigerated configuration to further enhance your flexibility.
