For drinking water, fluoridation systems, and industrial wastewater treatment, Industrial Fluoride Removal Process, the Hach EZ Series Fluoride Analysers provide reliable, continuous fluoride measurement using proven Ion Selective Electrode (ISE) technology with low-maintenance operation. Choose the EZ3008sc for stable, predictable water matrices, or the EZ3508sc for variable or complex samples where ionic strength and interferences can shift, supported by automated standard addition to help correct matrix effects.
Which Analyser Should I Choose?
The decision comes down to one factor: your water matrix. The simpler your matrix, the simpler your solution can be.
Choose the Hach EZ3008sc Fluoride Analyser (Direct ISE), measuring 0.1 - 1,000 mg/L F-, for stable, predictable water with consistent chemistry, such as municipal drinking water and fluoridation systems. Because this matrix has minimal interferences, direct ISE measurement delivers accurate, repeatable results with low maintenance and a lower total cost of ownership.
Choose the Hach EZ3508sc Fluoride Analyser (Direct ISE and Standard Addition), measuring 0.1 - 1,000 mg/L F-, for variable or complex water such as industrial process water, wastewater, and surface water, where shifting ionic strength and interfering ions like calcium and aluminium can distort direct readings. Its automated standard addition mode corrects for these interferences to deliver accurate, repeatable results in challenging conditions.
