Maximum uptime and reliability for TOC analysis in drinking water applications
The Hach BioTector B3500dw, with patented, EPA drinking water method approved Two Stage, Advanced Oxidation Technology, provides accurate results you can be confident in, including the capacity to measure Total Inorganic Carbon (TIC) in addition to TOC. This capability helps users achieve a more complete understanding of water quality. The analyzer gives you maximum reliability and uptime for drinking water applications. The analyzer typically requires maintenance only twice a year for standard items like reagent replenishment, pump tube replacement and calibration, making it an affordable TOC analyzer option.
Because the analyzer body has one of the most compact analyzer footprints available, plants can free up critical wall space that can be used for other instruments. The B3500dw is designed for long maintenance intervals, typically requiring reagent replenishment only once every six months instead of bi-weekly or monthly. In addition to TOC, this analyzer includes the capacity to measure Total Inorganic Carbon (TIC), offering a more complete view of your water quality. It also has the ability to monitor two streams at the same time and calculate % TOC removal, eliminating the need for two separate analyzers. The result is accurate, low cost analyzis you can rely on.
With maximum reliability and uptime along with low operating costs, the B3500dw provides immediate, direct savings and is the industry’s choice when it comes to TOC analyzis for drinking water applications. In addition to TOC analyzis, the B3500dw can also be configured to measure Total Inorganic Carbon (TIC), supporting a more comprehensive water quality assessment.
