Little Dipper 2
In-Line Fluorometer
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 Intuition controllers to monitor and control the level of treatment chemicals for cooling tower and boiler applications.
KEY BENEFITS
• Simple calibration with Walchem controllers
• Simple installation - now with built-in isolator
• Provides better control of treatment chemicals
• Solid-state LED/Photodiode technology, no moving parts
• Typical sensitivity to less than 1 ppb
• Quick-disconnect watertight connector
• Improved turbidity and dissolved iron rejection
