In-Process Nitrate Analyzer (Probe)
We are considering adding an in-process nitrate probe to our treatment process. Any suggestions? We have researched the HACH products. We have to "go out to bid" due to the cost of these systems, so I need some other manufacturers.
Thanks for any info.
This is more than a nitrate analyzer, Applied Spectrometry Associates Inc. "Chem Scan"
The ChemScan or equal is what is named in our spec book. Has anyone seen one of these work?
You might consider Biochem - some of my customers have had good luck with them.
You don't need a Chemscan unit to give you the data that you want. Hach and Endress+Hauser both have combination insitu probes that measure ammonia and nitrate. The both work equally well and are accurate enough for process control. None are "maintenance free" but much less maintenance and lower capital cost when compared to Chemscan.
We have ChemScan and have been very reliable. They also do ammonia and phosphorus, that is where the real value is. The Hach optical nitrate meter is simple and cheap if that is all you want.
