For years, Walchem has offered the WebMasterONE control in conjunction with Turner Designs Little Dipper online fluorometer, to accurately measure and control the concentration of scale or corrosion inhibitors in cooling tower and boiler applications. Now the Opti-Check fluorometer is available to ensure that the calibration of the online sensor is accurate. A low cost PTSA version, and an affordable PTSA/Fluorescein version, is available.
The Opti-Check handheld fluorometer requires low maintenance, is easy to use, and comes in a durable dustproof, watertight (IP 67) package. The product is sensitive to less than 1 ppb of fluorescent dye and provides better control of treatment chemicals.
