Q46F/D Direct Fluoride Monitor
Brand: Analytical Technology Inc/Q46F-D-Direct-Fluoride-Monitor/488524_Q46F_D_Direct_Fluoride_Monitor_2.jpg)
The Q46F/82 Direct Fluoride System is an on-line monitoring system designed for the continuous measurement of fluoride ion in solution.
The system is designed to measure fluoride ion directly without the use of chemical buffers and is suitable for potable water systems with stable pH and conductivity.
It is especially useful for applications where the use of chemicals is undesirable
Features- Easy to install
- Large, easy-to-read LCD display
- Can be supplied with the fluoride monitoring system factory mounted on a panel containing all necessary flow controls and a visual flow indicator
