Little Dipper™ 2 In-line Fluorometer
Turner Designs’ Little Dipper 2 is an accurate, single channel, light industrial fluorometer which installs directly into process streams. It is a rugged, 24/7 sampling device that provides an analog signal output proportional to the concentration of the fluorophore being measured. It can be used with controllers such as the W600 and W900 Series to monitor and control the level of treatment chemicals for cooling tower and boiler applications
