ChemScan is a well-established and US-based firm that produces a trusted line of analyzers for real-time drinking water and wastewater monitoring. ChemScan joined In-Situ Inc. in 2019. 

ChemScan mini Analyzer is a highly reliable, easy to use online colorimetric water analyzer family, which provides accurate analysis, real-time data and continuous monitoring for municipal drinking water and wastewater applications. The mini analyzer handles a single sample line and is available in a wide array of parameters and measurement ranges. Its industrial design, with sample tubing (ID) that is approximately 2X larger than competitive systems, minimizes the chance of plugging for exceptional reliability and lower maintenance. Its reliability combined with affordable reagents and spare parts results in a very low cost of ownership.
