Question
Does Hach offer any sensors with NSF certifications?
Summary
Availability of NSF certifications (NSF 61 for example) for Hach process sensors
Answer

Although Hach does not offer sensors that carry an NSF certification for in-line measuring, this should not automatically disqualify Hach's suite of analytical sensors from use.  NSF requirements are in place to ensure the safety of the consumer of the process solution from any leakage of potentially hazardous chemicals or particulates, so to comply with this requirement any sensor would have to be installed in a "slip stream" or branch line off of the process pipe and protected by a back flow prevention device.  All sample passing these sensors would have to be sent to a drain and not returned to the process.
