Walchem, IWAKI America Inc., has introduced the Opti-Check handheld fluorometer from Turner Designs. 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 low-maintenance, handheld fluorometer is easy to use and provides better control of treatment chemicals. Other features include a durable, dustproof, watertight (IP 67) package and sensitivity to less than 1 ppb of fluorescent dye.
